The Greatest Common Factor (GCF) of two or more integers is the largest positive integer that divides each of the integers without leaving a remainder.

This calculator uses the Prime Factorization Method:

1. Find the prime factorization of each number.
2. Identify all the prime factors that are common to all numbers.
3. For each common prime factor, take the one with the lowest exponent.
4. Multiply these common prime factors together to get the GCF.
