Find the GCF of 42m−28n

Answer 1

To find the greatest common factor (GCF) of 42m - 28n, we need to find the largest expression that can divide both 42m and 28n without leaving a remainder.

First, we can factor out the terms:
42m = 2 * 3 * 7 * m
28n = 2 * 2 * 7 * n

Now, we can identify the common factors between 42m and 28n:
Common factors: 2, 7

To find the GCF, we multiply the common factors together:
GCF = 2 * 7 = 14

Therefore, the GCF of 42m - 28n is 14.
