To factor the expression \( 8a - 28 \) using the greatest common factor (GCF), we first need to determine the GCF of the terms in the expression.
The terms are:
- \( 8a \)
- \( -28 \)
The coefficients are 8 and -28. The GCF of 8 and 28 is 4.
Now, we can factor out the GCF (which is 4) from the expression:
\[
8a - 28 = 4(2a - 7)
\]
Thus, the factored form of \( 8a - 28 \) is:
\[
4(2a - 7)
\]
