Course modified date: 5 Jun 2022

Learn about multiples and factors. This course is ideal for beginners.

Introduction
Multiplication is the action of repeated addition. 
When multiplying you are adding the same number again and again.
Here is an example:
5 + 5 + 5 = 3 times 5.

In the multiplication equation 3 times 5 = 15, the numbers 3 and 5 are factors, and the number 15 is the multiple.

Factors are whole numbers that can be multiplied together to give another number.
Factors are whole numbers that can exactly divide another number.
In a multiplication equation, factors are presented in pairs called factor pairs.
For example, in the multiplication equation 5 times 6 = 30:
• numbers 5 and 6 are factors of 30
• numbers 5 and 6 are a factor pair of 30
• number 5 can exactly divide number 30, into 6 

• number 6 can exactly divide number 30, into 5
