## Check if an integer is a multiple of another integer

**Find the multiples of an integer inside an interval of two integers**

**Find all the factors of a whole number**

**Check if an integer is a divisor of another integer**

## A multiple of an integer

A positive integer M is a multiple of another positive integer N, when we can find a third whole number p such that the product of P an N is equal to M.

Example: 8 is a multiple of 4 because the multiplication of 4 and 2 gives 8 as product (4 * 2 = 8).

Since 8 is a multiple of 4 then 4 is a factor of 8. 4 and 2 are both factors of 8.
