The first few multiples of 10 and 40 are (10, 20, 30, 40, 50, 60, 70, . . . ) and (40, 80, 120, 160, 200, 240, . . . ) respectively. There are 3 commonly used methods to find LCM of 10 and 40 – by division method, by prime factorization, and by listing multiples.
What are not the factors of 10?
The factors of 10 are 1, 2, 5, and 10. You can also look at this the other way around: if you can multiply two whole numbers to create a third number, those two numbers are factors of the third. 2 x 5 = 10, so 2 and 5 are factors of 10. 1 x 10 = 10, so 1 and 10 are also factors of 10.

What do you mean by multiples of 10?
Multiples of 10 are the products when an integer is multiplied by 10. Did you know that 10 is the sum of the first four consecutive whole numbers, that is, 1 + 2 + 3 + 4 = 10, and 10 is the sum of the first three prime numbers, that is, 2 + 3 + 5 = 10? Multiples of 10 are the easiest to memorize.
Which is a multiple of 5 and a factor of 20?
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. In Year 2, children are expected to recognise multiples of: 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.
