To find the GCF of any two numbers, you need to figure out what numbers each have in common, then you choose the largest one that each have in common as the GCF. In this case: 15: 1, 3, 5, 15...then you have 22: 1, 2, 11...Not really much in common except the number 1; that is your GCF in this case. Good luck!
