To factor the expression \(24e + 32f\) using the Greatest Common Factor (GCF), we first find the GCF of the coefficients 24 and 32.
The factors of 24 are: \(1, 2, 3, 4, 6, 8, 12, 24\)
The factors of 32 are: \(1, 2, 4, 8, 16, 32\)
The greatest common factor of 24 and 32 is 8.
Now we can factor the original expression:
\[ 24e + 32f = 8(3e + 4f) \]
So, the correct factored form is:
8(3e + 4f).
