How do I find the factors or divisors of the number 520,421,400?

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 520,421,400, 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.

1 520,421,400

Next, we take the number 520,421,400 and divide it by 2.

In this case, 520,421,400 ÷ 2 = 260,210,700

If the quotient is a whole number, then 2 and 260,210,700 are factors. Write them in the table below. If the quotient is not a whole number, skip to the next test.

1 2 260,210,700 520,421,400

Now, we try dividing 520,421,400 by 3.

520,421,400 ÷ 3 = 173,473,800

If the quotient is a whole number, then 3 and 173,473,800 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 3 173,473,800 260,210,700 520,421,400

Let's try dividing by 4.

520,421,400 ÷ 4 = 130,105,350

If the quotient is a whole number, then 4 and 130,105,350 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 4 130,105,350 173,473,800 260,210,700 520,421,400

We keep dividing by the next largest number, in this case the number 5. If the quotient of 520,421,400 ÷ 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:
