Question

How do you find all factors of 22?

Answer 1

All factors of 22 are:

`1, 2, 11, 22`

Explanation:

To find all factors of a certain number, you have to find all the numbers that it is divisible by. In this case the number is 22.

Every number is divisible by 1 and by itself, so two of the factors are:

`1` and `22`

Then continue to divide 22 by all numbers less than 22, or until two factors meet.

22 is an even number, therefore it is divisible by 2, so another two factors are:

`2` and `11`

22 is then not divisible by 3, 4, 5, 6, 7, 8, 9, or 10. The next number on the list is 11, and we already found that 11 is a factor of 22. Therefore you don't need to go any further.

So all factors of 22 are

`1, 2, 11, 22`
