Practice makes perfect
The greatest common factor (GCF) is the greatest number that is a factor of two or more numbers. The first step for finding a GCF is to list the factors of the numbers. Then we can find which one is the greatest.
Given Numbers Factors GCF
88 1, 2, 4, 8, 11, 22, 44, 88 8
112 1, 2, 4, 7, 8, 14, 16, 28, 56, 112 8

The GCF of 88 and 112 is 8.
