Answer 1

To factor the expression \(48y + 36z\) using the greatest common factor (GCF), we first need to find the GCF of the coefficients 48 and 36.

1. The prime factorization of 48 is \(2^4 \times 3\).
2. The prime factorization of 36 is \(2^2 \times 3^2\).

The GCF is found by taking the lowest power of each prime factor common to both numbers:
- For the prime \(2\), the lowest power is \(2^2\).
- For the prime \(3\), the lowest power is \(3^1\).

Thus, the GCF of 48 and 36 is:
\[
2^2 \times 3^1 = 4 \times 3 = 12.
\]

Now, we factor out 12 from the original expression:
\[
48y + 36z = 12(4y + 3z).
\]

So, the factored form of the expression is \(12(4y + 3z)\).

Therefore, the correct response is:
**12(4y + 3z)**.
