$28$

Step 1

The factors for

28

$28$ are all numbers between

- 28

$- 28$ and

28

$28$ , which divide

28

$28$ evenly.

Check numbers between

- 28

$- 28$ and

28

$28$

Step 2

Find the factor pairs of

28

$28$ where

x \cdot y = 28

$x \cdot y = 28$ .

\begin{matrix} x & y 1 & 28 2 & 14 4 & 7 - 1 & - 28 - 2 & - 14 - 4 & - 7 \end{matrix}

$\begin{array}{c} x & y \\ 1 & 28 \\ 2 & 14 \\ 4 & 7 \\ - 1 & - 28 \\ - 2 & - 14 \\ - 4 & - 7 \end{array}$

Step 3

List the factors for

28

$28$ .

- 28, - 14, - 7, - 4, - 2, - 1, 1, 2, 4, 7, 14, 28

$- 28, - 14, - 7, - 4, - 2, - 1, 1, 2, 4, 7, 14, 28$
