To solve the problem, we need to find the other factor when one factor is 1 and their product is 1.
Given:
- One factor = 1
- Product = 1
Let the other factor be \( x \). The equation can be set up as:
\[ 1 \times x = 1 \]
From this equation, we can conclude that:
\[ x = 1 \]
So, the other factor is 1.
The correct response is: "Yes; the other factor is 1 since 1 × 1 = 1."
