What is the greatest common factor of 9 and 42?
The GCF of 9 and 42 is 3. One way to determine the greatest common factor is to find all the factors of the numbers and compare them. The factors of 9 are 1, 3, and 9. The factors of 42 are 1, 2, 3, 6, 7, 14, 21, and 42. 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 9 are 3 and 3. The prime factors of 42 are 2, 3, and 7. The prime factors in common are a single 3, so the greatest common factor is 3.
What is the greatest common factor of 9 18 and 42?
The GCF of 9, 18, and 42 is 3.The factors of 9 = 3*3The factors of 18 = 2*3*3The factors of 42 = 2*3*7So the greatest common factor = 3.
What is the greatest common factor of 9 30 and 42?
Greatest common factor of 9 30 and 42 is 3.
What are the greatest common factors of 18 24 and 42?
The factors of 18 are:1, 2, 3, 6, 9, 18The factors of 42 are:1, 2, 3, 6, 7, 14, 21, 42The common factors are:1, 2, 3, 6The Greatest Common Factor:GCF = 6
What is the greatest common factor of 42 and 54?
The GCF of 45 and 54 is 6. The factors of 42 are 1,2,3,6, and 7 because these are the only numbers that will divide evenly into 42 with no remainder. The factors of 54 are 1,2,3,6, and 9. The common factors of these two numbers are 1,2,3, and 6 because they appear in both lists of factors. Of these common factors, 6 is the largest number. Therefore the greatest common factor for 42 and 54 is 6.
What is the greatest common factor of 42 and 126?
Answer: 42Definition: 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 the numbers have in common.Method: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 42 are 1, 2, 3, 6, 7, 14, 21, and 42.The factors of 126 are 1, 2, 3, 6, 7, 9, 14, 18, 21, 42, 63, and 126.The common factors are 1, 2, 3, 6, 7, 14, 21, and 42. Therefore, the greatest common factor is 42.
What are the highest common factors of18 and 42?

What are the common factors and greatest common factor of 9?
There is neither a greatest common factor nor common factors of a single number, such as 9, 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 9 are 1, 3, and 9. The prime factors of 9 are 3 and 3. Examples: The common factors of 9 and 24 are 1 and 3; the greatest common factor is 3. The common factors of 9 and 64 are only 1; the greatest common factor is 1. The common factors of 9 and 108 are 1, 3, and 9; the greatest common factor is 9.
What is the greatest common factor of 36 42 and 18?
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 36 are 1, 2, 3, 4, 6, 9, 12, 18, and 36. The factors of 42 are 1, 2, 3, 6, 7, 14, 21, and 42. The common factors are 1, 2, 3, and 6. Therefore, the greatest common factor is 6.
