  # Spot Factor Pairs

In this worksheet, students must identify the factor pairs for the given number. Key stage:  KS 2

Curriculum topic:   Number: Multiplication and Division

Curriculum subtopic:   Recognise/Use Pairs in Mental Calculation

Difficulty level:   #### Worksheet Overview

Two whole numbers that multiply together to give a number are a factor pair of that given number.

2 and 6 are a factor pair of 12 because 2 × 6 = 12.

But 12 has other factor pairs too.

3 and 4 are a factor pair of 12 because 3 × 4 = 12.

1 and 12 are the simplest factor pair because 1 × 12 = 12.

This means that:

12 =

1 × 12  and 12 × 1

2 × 6  and 6 × 2

3 × 4  and 4 × 3

Example

Which of these are a factor pair of 64?

3 and 18 or 4 and 16.

3 × 18 = 54

4 × 16 = 64

So 4 and 16 are a factor pair of 64.
