Using Factor Pairs to Divide

In this worksheet, you will learn to use factor pairs to help you divide larger numbers.

To answer the question 600 ÷ 3

We know that 2 × 3 = 6

We also know that 20 x 3 = 60

This means that 200 × 3 = 600.

So 600 ÷ 3 = 200.

Example 1

Use the factor pair 3 × 4 = 12 to work out 120 ÷ 30.

Answer

3 × 4 = 12

30 × 4 = 120

120 ÷ 30 = 4

Example 2

Use the factor pair 5 × 3 = 15 to work out 1500 ÷ 5.

Answer

5 × 3 = 15

5 x 30 = 150

5 × 300 = 1500

1500 ÷ 5 = 300
