What are the greatest common factors of 60 75 102?
There cannot be a greatest common factor (GCF) 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 does common number mean?
All numbers have factors. Some numbers have some of the same factors as other numbers. These are known as common factors because they are factors that the numbers have in common. 3 is a factor of 12. 3 is a factor of 15. 3 is a common factor of 12 and 15.
What are the two smallest numbers that have common factors of 2 3 4?
12 and 24
What is the greatest common factor of 43 and 81?
You need 2 or more numbers to do common factors, because it needs to be a factor which is COMMON to the numbers)The Greatest Common Factor (GCF), or Highest Common Factor (HCF), of two or more non-zero integers, is the largest positive integer that divides the numbers without a remainder.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 is a common factor-?
A common factor is a factor that is common to 2 or more numbers.Examples:Common factors of 4 and 6 are: 1 and 2Common factors of 15 and 25 are: 1 and 5Common factors of 16 and 24 are: 1, 2, 4, and 8.Common factors of 28 and 42 are: 1, 2, 7 and 14.A common factor is a number that will divide two or more other numbers without leaving a remainder. For example, 3 is a common factor of 3, 6, and 21.List the factors of two numbers. Any number that appears on both lists is a common factor.All numbers have factors. Some numbers have some of the same factors as other numbers. These are known as common factors. 2 is a common factor of 4 and 6.All non-zero numbers have factors. Some numbers have the same factors as other numbers. They are said to have those numbers "in common," which was shortened to common factors.
What does it mean for a number to be a common factor of two?
All numbers have factors. Some numbers have some of the same factors as other numbers. These are known as common factors. 3 is a factor of 9. 3 is a factor of 15. 3 is a common factor of 9 and 15.
What are the common factors and greatest common factor of 3?
There is neither a greatest common factor nor common factors of a single number, such as 3, 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 3 are 1 and 3. The prime factor of 3 is 3. Examples: The common factors of 3 and 20 are only 1; the greatest common factor is 1. The common factors of 3 and 81 are 1 and 3; the greatest common factor is 3.
What is the greatest common factor of 15 and 33?
Answer:The greatest common factor of 15 and 33 is 3.The common factors of 15 and 33 are 1 and 3.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 15 are 1, 3, 5, and 15.The factors of 33 are 1, 3, 11, and 33.The common factors are 1 and 3. Therefore, the greatest common factor is 3.The greatest common factor can also be calculated by identifying the common prime factors and multiplying them together.The prime factors of 15 are 3 and 5.The prime factors of 33 are 3 and 11.The prime factors in common are 3, so the greatest common factor is 3.
What is the greatest common factor for 9?
There is not a greatest common factor of 9 because there cannot be a greatest common factor without two or more numbers to compare. Common factors are factors that the numbers being compared have in common. The factors of 9 are 1, 3, and 9. The prime factors of 9 are 3 and 3.
What are the common factors of 15?
There are no common factors of 15 because there cannot be common factors without two or more numbers to compare. Common factors are factors that the numbers being compared have in common.The factors of 15 are 1, 3, 5, and 15.Examples:The common factors of 6 and 15 are 1 and 3.The common factors of 15 and 90 are 1, 3, 5, and 15.1,5,3, and 15.
What is the greatest common factor of 81?
There is not a greatest common factor of 81 because there cannot be a greatest 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.The factors of 81 are 1, 3, 9, 27, and 81.The prime factors of 81 are 3, 3, 3, and 3.Examples:The greatest common factor of 54 and 81 is 27.The greatest common factor of 81 and 117 is 9.You need at least two numbers to find a GCF.You need at least two numbers to find a GCF.
What are the first two common factors of 3 and 5?
Since 3 and 5 are both prime numbers, the only common factor of the two numbers is 1. Perhaps you are thinking of common multiples, the first two common multiples of the two numbers are 15 and 30.
What are two numbers that have common factors of 3 5 and 6?
30 and 60.
What are the greatest common factors of 45 and 81?
Short answer: There are none. There is neither a greatest common factor nor common factors of a single number, such as 81, 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 81 are 1, 3, 9, 27, and 81. Examples: The common factors of 18 and 81 are 1, 3, and 9; the greatest common factor is 9. The common factors of 20 and 81 are only 1; the greatest common factor is 1. The common factors of 39 and 81 are 1 and 3; the greatest common factor is 3. The common factors of 81 and 243 are 1, 3, 9, 27, and 81; the greatest common factor is 81.
What are the common factors of 138?
There are not common factors of 138 because there cannot be common factors without two or more numbers to compare. Common factors are factors that the numbers being compared have in common. The factors of 138 are 1, 2, 3, 6, 23, 46, 69, and 138.
What are two numbers that are factors of 3 and 5?
3 and 5 are both prime numbers and 1 is their only common factor.
What are the greatest common factors of 60 75 102?
There cannot be a greatest common factor (GCF) 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.
