A multiple is the result of multiplying a number by an integer (not by a fraction).

A common multiple is a multiple that is common to two or more numbers.

Explain how to identify a common multiple of two or more numbers

Maths

 In this unit pupils will explain how to identify a multiple or common multiple to solve problems in a range of contexts. In the future unit pupils will explain why the product stays the same when one factor is doubled and the other is halved and use knowledge of equivalence when scaling factors to solve problems.

In the prior unit pupils explained reasons for changing 2-factor multiplication calculations to 3-factor multiplications and explained what a factor is and how to use arrays and multiplication/division facts to find them. They identified prime numbers and composite numbers. In this unit pupils will explain how to identify a multiple or common multiple to solve problems in a range of contexts.

Use common factors and multiples to solve calculations efficiently

Write the number that would represent a multiple in this equation.       56 = 8 × 7

My number is between 30 and 40
It is a multiple of 2
It is a multiple of 6
4 is a factor of this number.
The sum of its digits add up to 9
What is my number?

Complete the missing word. factor × factor = {{  }}

Tick the number that is not a factor of 25

Tick the number that would represent a multiple in the equation 3 × 7 = 21

Write the number that would represent a multiple in this equation. 42 ÷ 6 = 7
