Multiples of 20
Methods
Methods for Finding Multiples:
For a beginner, you can find the multiples of a number by skip-counting to the next number. For Instance, if you want to find the multiples of 20, you could start at 20, and keep adding 20 over and over: 20, 40, 60, 80, and so on. Each of these numbers is a multiple of 20. Typically, this works best only for smaller numbers, as adding larger numbers together over and over can be difficult.
Another way to do this is to use multiplication. To find the first few multiples of 20, you could just multiply 20 by each number in sequence, first multiplying by 1, then 2, then 3, and so on, which we will outline below.
What are the Multiples of 20?
So, what are the multiples of 20? Let’s write it out using the multiplication method:
20
×
1
=
20
20 × 1 = 20
20 × 1 = 20
20
×
2
=
40
20 × 2 = 40
20 × 2 = 40
20
×
3
=
60
20 × 3 = 60
20 × 3 = 60
20
×
4
=
80
20 × 4 = 80
20 × 4 = 80
20
×
5
=
100
20 × 5 = 100
20 × 5 = 100
20
×
6
=
120
20 × 6 = 120
20 × 6 = 120
20
×
7
=
140
20 × 7 = 140
20 × 7 = 140
20
×
8
=
160
20 × 8 = 160
20 × 8 = 160
20
×
9
=
180
20 × 9 = 180
20 × 9 = 180
20
×
10
=
200
20 × 10 = 200
20 × 10 = 200
So, the first 10 multiples of 20 are: 20, 40, 60, 80, 100, 120, 140, 160, 180 and 200.
There are an endless number of multiples of 20. You could choose any number to multiply by 20 to find a new multiple!
Interesting Facts about Multiples
• Every number is considered the smallest multiple of itself.
• A multiple of a number is very often also the multiple of another number. This is because if you multiply two numbers together, the result is a multiple of both numbers.
• All multiples of even numbers are even.
• The multiples of odd numbers, in sequence, alternate between odd and even numbers.
• You can also find the negative multiples of a number by multiplying by negative numbers.
