To factor the expression \(24e + 32f\) using the greatest common factor (GCF), we first find the GCF of the coefficients 24 and 32.
The GCF of 24 and 32 is 8. Now, we can factor out 8 from the expression:
\[ 24e + 32f = 8(3e + 4f) \]
So, the correct factored form is:
\[ 8(3e + 4f) \]
The response is:
8(3e + 4f)
