# Multiples of 18

The multiples of 18 are obtained by multiplying integers with 18. In this section, we will learn about the multiples of 18. For more details about multiples, see our page “Multiples of a Number“.

## What are Multiples of 18?

A number is called a multiple of 18 if it is completely divisible by 18 with the remainder zero.

For example, 18 divides 36 completely, so by the definition 36 is a multiple of 18. Similarly, 18, 36, 54, 72, 190, 1900, etc. are all examples of multiples of 18 as they are completely divisible 18.

Remark: From the above definition, it is clear that any multiple of 18 can be written as 18n for some integer n. So the set of multiples of 18 is given by

{18n: n is an integer}. This is the set builder form of the multiples of 18.

## Properties of Multiples of 18

• Multiples of 18 are even numbers.

• Multiples of 18 always end with either 0, 2, 4, 6 or 8.

• If a number ends with either 1, 3, 5, 7 or 9, then that number cannot be a multiple of 18.
