Skill: Identify multiples of a number

A multiple is the answer you get when you multiply a number by a whole number, including $0$.

To check whether a number is a multiple of another number:

1. Multiply the given number by $(0, 1, 2, 3,\ldots)$, or count by that number.
2. See whether you reach the number you are checking.
3. You can also divide. If the quotient is a whole number with no remainder, it is a multiple.

Example: Is $(36)$ a multiple of $6$?

Count by $6$:

$$6,\ 12,\ 18,\ 24,\ 30,\ 36$$

You reached $(36)$, so $(36)$ is a multiple of $6$.

Using multiplication:

$$6 \times 6=36$$

Because $6$ was multiplied by the whole number $6$, $(36)$ is a multiple of $6$.

You can check with division:

$$36 \div 6=6$$

The answer is a whole number with no remainder, so $(36)$ is a multiple of $6$.
