To find the multiple of a number, add the number to itself.
To get multiples of 12, start at 12 and keep adding 12.
Even multiples of 5 must end with a zero.
They're all divisible by 4.
As a general rule, multiples tend to be larger than factors. This is not always true. 9 is a factor of 27. 6 is a multiple of 3. The important distinction is in the relationship to the number they are factors or multiples of. A factor will be equal to or lesser than the number. A multiple will be equal to or greater than the number.
