What are the common factors and greatest common factor of 18?
Short answer: There are none. There is neither a greatest common factor nor common factors of a single number, such as 18, because there cannot be any form of common factor without two or more numbers to compare. Common factors are factors that the numbers being compared have in common. The greatest common factor is the largest factor that all the numbers being compared have in common. Thus, since there are not two or more numbers to compare, there are neither common factors nor a greatest common factor. The factors of 18 are 1, 2, 3, 6, 9, and 18. Examples: The common factors of 18 and 24 are 1, 2, 3, and 6; the greatest common factor is 6. The common factors of 18 and 81 are 1, 3, and 9; the greatest common factor is 9. The common factors of 18 and 54 are 1, 2, 3, 6, 9, and 18; the greatest common factor is 18.
What is the greatest common factor of 18 and 18?
There cannot be a greatest common factor of just one number. To be common there need to be at least two numbers. If you find all the factors of two or more numbers, and you find some factors are the same ("common"), then the largest of those common factors is the Greatest Common Factor.
What are the common factors of 4 and 18?
Answer:The common factors of 4 and 18 are 1 and 2.The greatest common factor of 4 and 18 is 2.Definition: A factor is a divisor - a number that will evenly divide into another number. The common factors of two or more numbers are all the factors that the numbers have in common. The greatest common factor of two or more numbers is the largest factor that the numbers have in common.Methods:One way to determine the common factors and greatest common factor is to find all the factors of the numbers and compare them.The factors of 4 are 1, 2, and 4.The factors of 18 are 1, 2, 3, 6, 9, and 18.The common factors are 1 and 2; the greatest common factor is 2.The common factors and greatest common factor can also be calculated by identifying the common prime factors and multiplying them together to identify the greatest common factor, and then taking all the factors of it to determine the common factors.The prime factors of 4 are 2 and 2.The prime factors of 18 are 2, 3, and 3.The prime factors in common are a single 2, so the greatest common factor is 2. The factors of 2 are 1 and 2, which are the common factors.1 and 2
What are the common factors of 54?
Short answer: There are none. There is neither a greatest common factor nor common factors of a single number, such as 54, because there cannot be any form of common factor without two or more numbers to compare. Common factors are factors that the numbers being compared have in common. The greatest common factor is the largest factor that all the numbers being compared have in common. Thus, since there are not two or more numbers to compare, there are neither common factors nor a greatest common factor. Examples: The common factors of 4 and 54 are 1 and 2; the greatest common factors is 2. The common factors of 18 and 54 are 1, 2, 3, 6, 9, and 18; the greatest common factor is 18.
What are the greater common factor of18 and 36?
The Greatest Common Factor depends upon the numbers for which there are common factors and it is the greatest one of them; it can be greater than 18, for example the greatest common factor of 40 and 100 is 20. The greatest common factor must be one of the factors of each of the numbers. As the factors of each number cannot be greater than that number, the greatest common factor of a set of numbers cannot be greater than the least number. If this number is not greater than 18 then the greatest common factor of the numbers cannot be greater than 18. Even if the least number is greater than 18 it is possible that the greatest common factor of a set of numbers is still not greater than 18, for example the greatest common factor of 20, 30 and 50 is 10.
What is the greatest common factor of 18 26 and 32?
Answer:The greatest common factor of 18, 26, and 32 is 2.The common factors of 18, 26, and 32 are 1 and 2.Definition: A factor is a divisor - a number that will evenly divide into another number. The common factors of two or more numbers are all the factors that the numbers have in common. The greatest common factor of two or more numbers is the largest factor that the numbers have in common.Methods:One way to determine the common factors and greatest common factor is to find all the factors of the numbers and compare them.The factors of 18 are 1, 2, 3, 6, 9, and 18.The factors of 26 are 1, 2, 13, and 26.The factors of 32 are 1, 2, 4, 8, 16, and 32.The common factors are 1 and 2. Therefore, the greatest common factor is 2.The greatest common factor can also be calculated by identifying the common prime factors and multiplying them together.The prime factors of 26 are 2 and 13.The prime factors of 18 are 2, 3, and 3.The prime factors of 32 are 2, 2, 2, 2, and 2.The only common prime factor is 2, so the greatest common factor is 2.Note: The common factors are the factors of the greatest common factor, so the common factors are 1 and 2.
What is the greatest common factor of 36 and 90?
The greatest common factor of 36 and 90 is 18.The common factors of 36 and 90 are 1, 2, 3, 6, 9, and 18.Definition: A factor is a divisor - a number that will evenly divide into another number. The common factors of two or more numbers are all the factors that the numbers have in common. The greatest common factor of two or more numbers is the largest factor that the numbers have in common.Methods:One way to determine the common factors and greatest common factor is to find all the factors of the numbers and compare them.The factors of 36 are 1, 2, 3, 4, 6, 9, 12, 18, and 36.The factors of 90 are 1, 2, 3, 5, 6, 9, 10, 15, 18, 30, 45, and 90.The common factors are 1, 2, 3, 6, 9, and 18. Therefore, the greatest common factor is 18.The greatest common factor can also be calculated by identifying the common prime factors and multiplying them together.The prime factors of 36 are 2, 2, 3, and 3.The prime factors of 90 are 2, 3, 3, and 5.The prime factors in common are 2, 3, and 3, so the greatest common factor is 2 x 3 x 3 = 18.
What are the greatest common factors of 18 and 36?
18 is the greatest common factor.
What is the greatest common factor for 18 and 33?
The factors of 18 are 1, 2, 3, 6, 9, and 18.The factors of 33 are 1, 3,11, and 33.The factors that are common to both numbers are 1 and 3.The greatest one is 3 .
What is the greatest common factor of 18 27 and 81?
A factor is a divisor - a number that will evenly divide into another number. The greatest common factor of two or more numbers is the largest factor that both numbers have in common. One way to determine the common factors and greatest common factor is to find all the factors of the numbers and compare them. The factors of 18 are 1, 2, 3, 6, 9, and 18. The factors of 27 are 1, 3, 9, and 27. The factors of 81 are 1, 3, 9, 27, and 81. The common factors are 1, 3, and 9. Therefore, the greatest common factor is 9.
what is the largest factor that two numbers share is called?
The greatest common factor (GCF) of two (or more) numbers is the greatest factor that divides two numbers. To find the GCF you must work out and list the prime factors of each of the numbers. You will see that the numbers have prime factors in common. Multiply those factors the numbers have in common together and this gives you the GCF for the numbers. eg Number A = 18, Prime factors = 2*3*3 Number B = 24, Prime factors = 2*2*2*3 The Prime factors that A and B have in common are 2 and 3 Multiply them together = 6 6= the GCF of 18 and 24
Why are greatest common factors always even numbers?
They aren't. The GCF of 18 and 21 is 3.
