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 \(4(2a - 7)\).
Factor 8a − 28 using the GCF.(1 point)
