Factor 8a − 28 using the GCF.(1 point)

Answer 1

To factor the expression \(8a - 28\) using the greatest common factor (GCF), we first need to determine what the GCF of the coefficients and terms is.

Let's look at the numbers:

The coefficient of \(a\) is 8, and the other term is 28. The greatest common factor of 8 and 28 is 4 (the largest number that divides into both 8 and 28 without leaving a remainder).

Now let's factor out the GCF:

\(8a - 28 = 4(2a) - 4(7)\)

Factor out the 4:

\(8a - 28 = 4(2a - 7)\)

So the expression \(8a - 28\) factored using the GCF is \(4(2a - 7)\).
