# Is 40 Divisible By 8?

In this quick and easy guide, we'll work out whether 40 is divisible by 8. 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 "40 is divisible by 8". What we want to check is whether 40 can be divided by 8 without any remainder (i.e the answer is a whole number).

With smaller numbers, checking divisibility by 8 is easiest by just mentally doing your 8 times table and seeing if 40 is part of it. For larger numbers, you can take the last 3 digits and check whether that number (in this case 40) is divisible by 8. If it is, then 40 is too.

In this case, we can see that 40 IS divisible by 8, which means that **40 IS divisible by 8 too.**

Another way you can figure out if 40 is divisible by 8 is by actually doing the calculation and dividing 40 by 8:

Since the answer to our division is a whole number, we know that 40 is divisible by 8.

Hopefully now you know exactly how to work out whether one number is divisible by another. Could I have just told you to divide 40 by 8 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.
