11 left parenthesis 2 plus 5 right parenthesis

2(11+5)
2 left parenthesis 11 plus 5 right parenthesis

11(2×5)
11 left parenthesis 2 times 5 right parenthesis

1(22+55)

Answer 1

To rewrite \( 22 + 55 \) using their greatest common factor (GCF), we first need to determine the GCF of 22 and 55.

The GCF of 22 and 55 can be found as follows:

- The prime factorization of 22 is \( 2 \times 11 \).
- The prime factorization of 55 is \( 5 \times 11 \).

The common factor is \( 11 \).

Now we can express the original sum \( 22 + 55 \) as:

\[
22 + 55 = 11(2 + 5)
\]

So the correct response is:

**11(2 + 5)**.
