To find the greatest common factor (GCF) of 42m-28n, we need to identify the common factors of both terms and find the greatest one.
First, let's factor out the greatest common factor from each term:
42m = 2 * 3 * 7 * m
28n = 2 * 2 * 7 * n
The common factors are 2, 7, and m. Since we're looking for the greatest common factor, we can multiply these common factors together:
GCF = 2 * 7 * m = 14m
Therefore, the GCF of 42m-28n is 14m.
