   What is the greatest common factor of numbers?

   • GCF (5,0) = 5 and more generally GCF (k,0) = k for any whole number k. However, GCF (0, 0) is undefined. 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.

   What is the greatest common factor of a set of whole numbers?

   • The greatest common factor (GCF or GCD or HCF) of a set of whole numbers is the largest positive integer that divides evenly into all numbers with zero remainder. For example, for the set of numbers 18, 30 and 42 the GCF = 6. Any non zero whole number times 0 equals 0 so it is true that every non zero whole number is a factor of 0.

   How do you find the greatest common factor (GCF)?

   • If you have a greatest common factor calculator, then this would be a breeze. But if you need to work by hand, finding the GCF would take a lot of time. That is unless you use Euclid’s Algorithm. Here’s how: Start with two whole numbers and subtract the smaller one from the larger one. Take note of the result.
