Greatest common factor (GCF) of 3 and 8 is 1. We will now calculate the prime factors of 3 and 8, than find the greatest common factor (greatest common divisor (gcd)) of the numbers by matching the biggest common factor of 3 and 8.

When we find all the factors of two or more numbers, and some factors are the same ("common"), then the largest of those common factors is the Greatest Common Factor. Example: the GCF of 12 and 16 is 4, because 1, 2 and 4 are common factors of both 12 and 16, and 4 is the greatest of them.

Greatest common factor (GCF) of 2 and 6 is 2. We will now calculate the prime factors of 2 and 6, than find the greatest common factor (greatest common divisor (gcd)) of the numbers by matching the biggest common factor of 2 and 6.

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.
