How do I find the factors or divisors of the number 400,224,252?

Unfortunately, there's not simple formula to identifying all of the factors of a number and it can be a tedious process when trying to identify the factors of larger numbers. To find the factors of the number 400,224,252, it is easiest to start from the outside in. Here's what we mean:

Outside in Factoring

We start by creating a table and writing 1 on the left side and then the number we're trying to find the factors for on the right side in a table.

1 400,224,252

Next, we take the number 400,224,252 and divide it by 2.

In this case, 400,224,252 ÷ 2 = 200,112,126

If the quotient is a whole number, then 2 and 200,112,126 are factors. Write them in the table below. If the quotient is not a whole number, skip to the next test.

1 2 200,112,126 400,224,252

Now, we try dividing 400,224,252 by 3.

400,224,252 ÷ 3 = 133,408,084

If the quotient is a whole number, then 3 and 133,408,084 are factors. Write them in the table below. If the quotient is not a whole number, skip to the next test.

Here is what our table should look like at this step:

1 2 3 133,408,084 200,112,126 400,224,252

Let's try dividing by 4.

400,224,252 ÷ 4 = 100,056,063

If the quotient is a whole number, then 4 and 100,056,063 are factors. Write them in the table below. If the quotient is not a whole number, skip to the next test.

Here is what our table should look like at this step:

1 2 3 4 100,056,063 133,408,084 200,112,126 400,224,252

We keep dividing by the next largest number, in this case the number 5. If the quotient of 400,224,252 ÷ 5 is a whole number, then 5 and your quotient are factors of the number.


Keep dividing by the next highest number until you cannot divide anymore.


What you will end up with is this table:

123461273146219292438876456,877913,7541,370,6311,827,5082,741,2625,482,52433,352,02166,704,042100,056,063133,408,084200,112,126400,224,252

All of the numbers in the table above can be evenly divided into the number 400,224,252.
