40

$40$ evenly.

Check numbers between

- 40

$- 40$ and

40

$40$

Step 2

Find the factor pairs of

40

$40$ where

x \cdot y = 40

$x \cdot y = 40$ .

\begin{matrix} x & y 1 & 40 2 & 20 4 & 10 5 & 8 - 1 & - 40 - 2 & - 20 - 4 & - 10 - 5 & - 8 \end{matrix}

$\begin{array}{c} x & y \\ 1 & 40 \\ 2 & 20 \\ 4 & 10 \\ 5 & 8 \\ - 1 & - 40 \\ - 2 & - 20 \\ - 4 & - 10 \\ - 5 & - 8 \end{array}$

Step 3

List the factors for

40
