Multiples of 645
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 645, you could just multiply 645 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 645, start at 645 and keep adding 645 over and over: 645, 1290, 1935, 2580, and so on. Each of these numbers is a multiple of 645.
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 645?
Let’s find the first 10 multiples of 645 by multiplying:
645
∗
1
=
645
645 * 1 = 645
645 ∗ 1 = 645
645
∗
2
=
1290
645 * 2 = 1290
645 ∗ 2 = 1290
645
∗
3
=
1935
645 * 3 = 1935
645 ∗ 3 = 1935
645
∗
4
=
2580
645 * 4 = 2580
645 ∗ 4 = 2580
645
∗
5
=
3225
645 * 5 = 3225
645 ∗ 5 = 3225
645
∗
6
=
3870
645 * 6 = 3870
645 ∗ 6 = 3870
645
∗
7
=
4515
645 * 7 = 4515
645 ∗ 7 = 4515
645

=
5160
645 * 8 = 5160
645 ∗ 8 = 5160
645
∗
9
=
5805
645 * 9 = 5805
645 ∗ 9 = 5805
645
∗
10
=
6450
645 * 10 = 6450
645 ∗ 10 = 6450
So, the first 10 multiples of 645 are: 645, 1290, 1935, 2580, 2580, 3870, 4515, 5160, 5805 and 6450.
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.
