To factor \(48y + 36z\) using the greatest common factor (GCF), we first need to determine the GCF of the coefficients 48 and 36.
- The factors of 48 are: \(1, 2, 3, 4, 6, 8, 12, 16, 24, 48\)
- The factors of 36 are: \(1, 2, 3, 4, 6, 9, 12, 18, 36\)
The greatest common factor of 48 and 36 is \(12\).
Next, we can factor out the GCF \(12\) from the expression \(48y + 36z\):
\[ 48y + 36z = 12(4y + 3z) \]
So, the correct factored form is:
\[ 12(4y + 3z) \]
Therefore, the correct response is:
12(4y + 3z)
