Question

What are the factors of 16?

Answer 1

See explanation.

Explanation:

To find all factors of a number you have to check if a number is divisible by prime numbers starting from the lowest (2).

`16` is an even number, so you can start by dividing by `2`.
`16-:2=8`

`8` is also even, so you can repeat the procedure:

`8-:2=4`
`4-:2=2`
`2-:2=1`

So we can write that `16=2^4`.

Therfore the factors of `16` are: `1,2,4,8` and `16`.
