80

$80$ , which divide

80

$80$ evenly.

Check numbers between

- 80

$- 80$ and

80

$80$

Step 2

Find the factor pairs of

80

$80$ where

x \cdot y = 80

$x \cdot y = 80$ .

\begin{array}{c} x & y \\ 1 & 80 \\ 2 & 40 \\ 4 & 20 \\ 5 & 16 \\ 8 & 10 \\ - 1 & - 80 \\ - 2 & - 40 \\ - 4 & - 20 \\ - 5 & - 16 \\ - 8 & - 10 \end{array}

$\begin{array}{c} x & y \\ 1 & 80 \\ 2 & 40 \\ 4 & 20 \\ 5 & 16 \\ 8 & 10 \\ - 1 & - 80 \\ - 2 & - 40 \\ - 4 & - 20 \\ - 5 & - 16 \\ - 8 & - 10 \end{array}$

Step 3
