Multiples of 18
Methods
Methods for Finding Multiples:
The most common way to find multiples is to use multiplication. Multiplication of whole numbers always results in multiples of the numbers being multiplied. To find the first few multiples of 18, you could just multiply 18 by 1, then 2, then 3, and so on, until you have as many multiples as you would like. This is shown in the next section.
For younger students that don’t know how to multiply yet, the same result can be found just by counting, or skip-counting. To find multiples of any number, just add the number to itself multiple times. For instance, if you want to find the multiples of 18, start at 18 and keep adding 18 over and over: 18, 36, 54, 72, and so on. Each of these numbers is a multiple of 18.
There are an endless number of multiples! You can keep using either of these methods to find as many multiples as you would like.
What are the Multiples of 18?
Let’s find the first 10 multiples of 18 by multiplying:
18
∗
1
=
18
18 * 1 = 18
18 ∗ 1 = 18
18
∗
2
=
36
18 * 2 = 36
18 ∗ 2 = 36
18
∗
3
=
54
18 * 3 = 54
18 ∗ 3 = 54
18
∗
4
=
72
18 * 4 = 72
18 ∗ 4 = 72
18
∗
5
=
90
18 * 5 = 90
18 ∗ 5 = 90
18
∗
6
=
108
18 * 6 = 108
18 ∗ 6 = 108
18
∗
7
=
126
18 * 7 = 126
18 ∗ 7 = 126
18
∗
8
=
144
18 * 8 = 144
18 ∗ 8 = 144
18

9
=
162
18 * 9 = 162
18 ∗ 9 = 162
18
∗
10
=
180
18 * 10 = 180
18 ∗ 10 = 180
So, the first 10 multiples of 18 are: 18, 36, 54, 72, 72, 108, 126, 144, 162 and 180.
Interesting Facts about Multiples
• The primary multiple of any number is itself.
• The result of any multiplication of whole numbers is a multiple of all the numbers being multiplied together. As such, every multiple is also a multiple of another number.
• Every multiple of even numbers will also be even.
• The successive multiples of odd numbers alternate between odd and even numbers.
• You can also find negative multiples of a number by multiplying by negative numbers.
