Question

Factor expression 12p-28 factored using GCF is?

Answer 1

4(3p - 7)

Explanation:

First find the factors of 12 and 28:

12: 1, 2, 3, 4, 6, 12

28: 1, 2, 4, 7, 28

Notice any common factors: 1, 2, 4

Now, out of these factors, 4 is the GCF since it is the greatest common factor, so divide 12 and 28 by 4:

12/4 = 3. 28/4 = 7.

Hence, 12p-28 = 4(3p - 7)
