When answering a question such as "Name two numbers whose GCF is 6" there are two quick and easy ways to do this. One is to name 6 and any multiple of 6. The other is to name any multiples of 6 that differ by 6.
You can find the GCF of two numbers by dividing their product by their LCM. The LCM of 30 and 42 is 210. What is their GCF? 30 x 42 = 1260 divided by 210 = 6 The GCF of 30 and 42 is 6.
You need at least two numbers to find a GCF. If that's 72 and 96, the GCF is 24.

To find a pair of numbers with a given GCF, take the GCF number and double it. The pair of numbers is the GCF, and two times the GCF. For instance, two numbers with a GCF of 3 are 3 and 6.
