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 420, you could start at 420, and keep adding 420 over and over: 420, 840, 1260, 1680, and so on. Each of these numbers is a multiple of 420. 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 420, you could just multiply 420 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 420?

So, what are the multiples of 420? Let’s write it out using the multiplication method:

420×1=420420 × 1 = 420

420×2=840420 × 2 = 840

420×3=1260420 × 3 = 1260

420×4=1680420 × 4 = 1680

420×5=2100420 × 5 = 2100

420×6=2520420 × 6 = 2520

420×7=2940420 × 7 = 2940

420×8=3360420 × 8 = 3360

420×9=3780420 × 9 = 3780

420×10=4200420 × 10 = 4200

So, the first 10 multiples of 420 are: 420, 840, 1260, 1680, 2100, 2520, 2940, 3360, 3780 and 4200.

There are an endless number of multiples of 420. You could choose any number to multiply by 420 to find a new multiple!

Interesting Facts Shared by a Math Tutor about Multiples
