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 132 are 1, 2, 3, 4, 6, 11, 12, 22, 33, 44, 66, and 132.
The factors of 156 are 1, 2, 3, 4, 6, 12, 13, 26, 39, 52, 78, and 156.
The common factors are 1, 2, 3, 4, 6, and 12. Therefore, the greatest common factor is 12.

It is: 39
What is the greatest common factor of 78 91 156?
The GCF is 13.
What are the common factors and greatest common factor of 156?
There is neither a greatest common factor nor common factors of a single number, such as 156, 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.
What is the greatest common factor of 156 and 204?
The greatest common factor (GCF) of two numbers is the largest number that can evenly divide both numbers. To find the GCF of 156 and 204, we first need to find the prime factorization of each number. 156 = 2^2 * 3 * 13 and 204 = 2^2 * 3 * 17. The GCF is the product of the common prime factors raised to the lowest power, which in this case is 2^2 * 3 = 12. Therefore, the greatest common factor of 156 and 204 is 12.
