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.

Does that help you solve the problem?

We are happy to help, but we won't do the work for you, you have to figure it out, that's the only way you'll learn. So tell us what you think, and why, and we're willing to lead you in the right direction, but we won't just give you the answer.
