TheSchoolRun.com closure date
As we informed you a few months ago, TheSchoolRun has had to make the difficult decision to close due to financial pressures and the company has now ceased trading. We had hoped to keep our content available through a partnership with another educational provider, but this provider has since withdrawn from the agreement.
As a result, we now have to permanently close TheSchoolRun.com. However, to give subscribers time to download any content they’d like to keep, we will keep the website open until 31st July 2025. After this date, the site will be taken down and there will be no further access to any resources. We strongly encourage you to download and save any resources you think you may want to use in the future.
In particular, we suggest downloading:
- Learning packs
- All the worksheets from the 11+ programme, if you are following this with your child
- Complete Learning Journey programmes (the packs below include all 40 worksheets for each programme)
You should already have received 16 primary school eBooks (worth £108.84) to download and keep. If you haven’t received these, please contact us at [email protected] before 31st July 2025, and we will send them to you.
We are very sorry that there is no way to continue offering access to resources and sincerely apologise for the inconvenience caused.
What are multiples and factors?
What are multiples and factors?
A multiple is a number that can be divided by another number a certain number of times without a remainder.
A factor is one of two or more numbers that divides a given number without a remainder.
Multiples and factors are best explained by using a number sentence such as the following:
This number sentence tells us that 20 is a multiple of 5 and is also a multiple of 4.
It also tells us that 5 and 4 are factors of 20.
By Year 4, when children have learnt all their times tables they should be able to recognise multiples of any number up to 10.
For example, they may be given a number such as 24 and asked if it is a multiple of the following numbers: 10, 2, 5, 8, 6. Their knowledge of times tables should help them to work out that 24 is a multiple of 2, 8 and 6.
Children also learn about factors in Year 4.
They may be asked to identify pairs of factors of two-digit numbers.
- For example: they may be given the number 60 and asked to pick out two pairs of factors from the following numbers: 7, 3, 9, 8, 15, 4, 20. (The answer to this is 3 x 20 and 4 x 15.)
- They may also need to find common multiples. For example: they may be given the numbers 6 and 9 and asked to find three multiples that have both these numbers as factors. (The three numbers could be: 54, 18 and 36.)
In Year 5, children will continue to carry out tasks involving factors and multiples and this will extend to learning about prime numbers and square numbers.
Example investigations for Year 6 children could be:
Two factors of 90 are added together to make another factor of 90. What are the two factors?
What am I? I am a multiple of 4. I am between 25 and 50. I am also a multiple of 10.
Two square numbers are added together to make a multiple of 9. What could the two square numbers be?
By Year 6 children need to be really confident not only on knowing what factors and multiples are, but also on quickly working out the factors and multiples of various numbers. This means they can take quickly to these sorts of puzzles. They might able be asked to find the lowest common multiple or highest common factor of two numbers or a group of numbers.
Multiples and factors in KS1 and KS2
In Year 2, children are expected to recognise multiples of:
- 2 (these are 2, 4, 6, 8, 10, 12 etc.)
- 5 (these are 5, 10, 15, 20, 25 etc.)
- and 10 (these are 10, 20, 30, 40, 50 etc.).
The foundation for this knowledge is started in Year 1 where children practise counting in 2s, 5s and 10s.
In Year 3, children need to be able to recognise multiples of 2, 5 and 10 up to 1000.
They would be taught the rule that any number that has a last digit that is even (24, 68, 102. 888 etc) is a multiple of 2. They would also learn that any number ending in a 5 or 0 (25, 300, 605, 990 etc.) is a multiple of 5. And finally, any number that ends in a 0 (20, 800, 450 etc.) is a multiple of 10.
By Year 4, when children have learnt all their times tables they should be able to recognise multiples of any number up to 10.
For example, they may be given a number such as 24 and asked if it is a multiple of the following numbers: 10, 2, 5, 8, 6. Their knowledge of times tables should help them to work out that 24 is a multiple of 2, 8 and 6.
Children also learn about factors in Year 4.
They may be asked to identify pairs of factors of two-digit numbers.
- For example: they may be given the number 60 and asked to pick out two pairs of factors from the following numbers: 7, 3, 9, 8, 15, 4, 20. (The answer to this is 3 x 20 and 4 x 15.)
- They may also need to find common multiples. For example: they may be given the numbers 6 and 9 and asked to find three multiples that have both these numbers as factors. (The three numbers could be: 54, 18 and 36.)
In Year 5, children will continue to carry out tasks involving factors and multiples and this will extend to learning about prime numbers and square numbers.
Example investigations for Year 6 children could be:
Two factors of 90 are added together to make another factor of 90. What are the two factors?
What am I? I am a multiple of 4. I am between 25 and 50. I am also a multiple of 10.
Two square numbers are added together to make a multiple of 9. What could the two square numbers be?
By Year 6 children need to be really confident not only on knowing what factors and multiples are, but also on quickly working out the factors and multiples of various numbers. This means they can take quickly to these sorts of puzzles. They might able be asked to find the lowest common multiple or highest common factor of two numbers or a group of numbers.
