Is 18 Divisible By 2?

In this quick and easy guide, we'll work out whether 18 is divisible by 2. There are some simple rules we can follow to decide whether one number is divisible by another without ever needing to even do the division!

First up, let's clarify what we mean by "18 is divisible by 2". What we want to check is whether 18 can be divided by 2 without any remainder (i.e the answer is a whole number).

There are a bunch of very similar methods for working out whether 18 is divisible by 2 but the easiest way to figure it out is to check whether 18 is an even number. If it is, then it is divisible by 2.

In this case, 18 is an even number, which means that it is divisible by 2.

You could also work this out by checking if the last digit of 18 ends with 2, 4, 6, 8, or 0. If it does, then it is divisible by two.

Another way you can figure out if 18 is divisible by 2 is by actually doing the calculation and dividing 18 by 2:

18 / 2 =   9

Since the answer to our division is a whole number, we know that 18 is divisible by 2.

Hopefully now you know exactly how to work out whether one number is divisible by another. Could I have just told you to divide 18 by 2 and check if it is a whole number? Yes, but aren't you glad you learned the process?

Give this a go for yourself and try to calculate a couple of these without using our calculator. Grab a pencil and a piece of paper and pick a couple of numbers to try it with.
