Methods for Finding Multiples: from a Math Tutor
For a beginner, a math tutor suggests that 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.

Interesting Facts Shared by a Math Tutor 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.
