# Factors of 400 in Pairs

So you need to find the factor pairs for 400 do you? Fear not! In this quick guide we'll describe what the factor pairs of 400 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 400. In proper math terms, the number 400 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 400 we need to first get all of the factors of 400. 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 400 are 1, 2, 5, 8, 10, 16, 20, 25, 40, 50, 80, 100, 200, and 400.

## List of Factor Pairs for 400

Okay, so we know all of the factors for 400 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 400.

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 400 for you automatically:

• 1 x 400 = 400
• 2 x 200 = 400
• 5 x 80 = 400
• 8 x 50 = 400
• 10 x 40 = 400
• 16 x 25 = 400
• 20 x 20 = 400
• 25 x 16 = 400
• 40 x 10 = 400
• 50 x 8 = 400
• 80 x 5 = 400
• 100 x 4 = 400
• 200 x 2 = 400
• 400 x 1 = 400
