Find the GCF of 42m−28n .(1 point) Responses 2 2 84 84 7 7 14

Answer 1

To find the greatest common factor (GCF) of the expression \(42m - 28n\), we first determine the GCF of the coefficients (42 and 28).

1. List the factors:

   • Factors of 42: 1, 2, 3, 6, 7, 14, 21, 42
   • Factors of 28: 1, 2, 4, 7, 14, 28

2. Find the common factors:

   • Common factors: 1, 2, 7, 14

3. Identify the greatest common factor:

   • The greatest common factor is 14.

Thus, the GCF of \(42m - 28n\) is 14.
