Answer 1

To rewrite the sum \( 25 + 45 \) using their greatest common factor (GCF) and multiplication, we first need to find the GCF of 25 and 45.

The factors of 25 are: \( 1, 5, 25 \)

The factors of 45 are: \( 1, 3, 5, 9, 15, 45 \)

The GCF of 25 and 45 is \( 5 \).

Now, we can express \( 25 + 45 \) in terms of the GCF:

\[
25 = 5 \times 5
\]
\[
45 = 5 \times 9
\]

This gives us:

\[
25 + 45 = 5 \times 5 + 5 \times 9 = 5(5 + 9)
\]

Thus, we can rewrite \( 25 + 45 \) as:

\[
70 = 5(5 + 9)
\]

So, the final answer would be:

\[
5(5 + 9)
\]
