The GCF is 5.
31. Factor each number: 62 = 2 x 31 217 = 7 x 31 155 = 5 x 31. The only factor that is common to all three numbers (and thus, the greatest common factor) is 31.
Well, darling, the highest common factor of 77 and 217 is 7. It's as simple as that. No need to complicate things, honey. Just remember to keep it sassy and straightforward, okay?
