So you need to find the factor pairs for 40 do you? Fear not! In this quick guide we'll describe what the factor pairs of 40 are, how you find them and list them out for you to prove the calculation works. Let's dive in!
What Are Factor Pairs?
A factor pair is a combination of two factors which can be multiplied together to equal 40. In proper math terms, the number 40 is called the product and the two numbers that can be multiplied together to equal it are called the factors.
In order to work out the factor pairs of 40 we need to first get all of the factors of 40. Once you have the list of all those factors we can pair them together to list out all of the factor pairs.
The complete list of factors for 40 are 1, 2, 4, 5, 8, 10, 20, and 40.
List of Factor Pairs for 40
Okay, so we know all of the factors for 40 now and to work out the factor pairs we can go through that list and find all of the different combinations that can be used to multiply together to result in 40.
If there are a lot of factors then it might take you a little while to calculate all of the factor pairs, but luckily we have the power of computers and can calculate the factor pairs of 40 for you automatically:
- 1 x 40 = 40
- 2 x 20 = 40
