The greatest common factor (GCF) of a set of numbers is the largest factor that all the numbers share. For example, 12, 20, and 24 have two common factors: 2 and 4. The largest is 4, so we say that the GCF of 12, 20, and 24 is 4. GCF is often used to find common denominators.

To find the GCF, take the prime factorization of both numbers. Then write down the factors that they have in common. If they share more than one of the same factor (two 2's, for example), write them both down. Then multiply the factors they have in common.
