Answer 1

To factor 8a - 28 using the greatest common factor (GCF), we first need to find the largest number that can divide both 8a and 28 evenly.

The GCF of 8a and 28 is 4, which means we can divide both terms by 4.

First, let's factor out a common factor of 4:
4(2a - 7)

So, the factored form of 8a - 28 using the GCF is 4(2a - 7).
