Multiples of 45
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 45, you could start at 45, and keep adding 45 over and over: 45, 90, 135, 180, and so on. Each of these numbers is a multiple of 45. 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 45, you could just multiply 45 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 45?
So, what are the multiples of 45? Let’s write it out using the multiplication method:
45
×
1
=
45
45 × 1 = 45
45 × 1 = 45
45
×
2
=
90
45 × 2 = 90
45 × 2 = 90
45
×
3
=
135
45 × 3 = 135
45 × 3 = 135
45
×
4
=
180
45 × 4 = 180
45 × 4 = 180
45
×
5
=
225
45 × 5 = 225
45 × 5 = 225
45
×
6
=
270
45 × 6 = 270
45 × 6 = 270
45
×
7
=
315
45 × 7 = 315
45 × 7 = 315
45
×
8
=
360
45 × 8 = 360
45 × 8 = 360
45
×
9
=
405
45 × 9 = 405
45 × 9 = 405
45
×
10
=
450
45 × 10 = 450
45 × 10 = 450
So, the first 10 multiples of 45 are: 45, 90, 135, 180, 225, 270, 315, 360, 405 and 450.
There are an endless number of multiples of 45. You could choose any number to multiply by 45 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.
