Any non zero whole number times 0 equals 0 so it is true that every non zero whole number is a factor of 0. In this example, 5 and 0 are factors of 0. There are several ways to find the greatest common factor of numbers. The most efficient method you use depends on how many numbers you have, how large they are and what you will do with the result. To find the GCF by factoring, list out all of the factors of each number or find them with a Factors Calculator. The whole number factors are numbers that divide evenly into the number with zero remainder. Given the list of common factors for each number, the GCF is the largest number common to each list.

Approach 1. Integer numbers prime factorization. Approach 2. Euclid's algorithm. Euclid's algorithm: Step 1. This is the greatest common factor divisor. If "t" is a factor divisor of "a" then among the prime factors of the prime factorization of "t" will appear only prime factors that also appear in the prime factorization of "a", and the maximum of their exponents is at most equal to those involved in the prime factorization of "a".
