How do I find the factors or divisors of the number 421,165,252?

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 421,165,252, 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.

1 421,165,252

Next, we take the number 421,165,252 and divide it by 2.

In this case, 421,165,252 ÷ 2 = 210,582,626

If the quotient is a whole number, then 2 and 210,582,626 are factors. Write them in the table below. If the quotient is not a whole number, skip to the next test.

1 2 210,582,626 421,165,252

Now, we try dividing 421,165,252 by 3.

421,165,252 ÷ 3 = 140,388,417.3333

If the quotient is a whole number, then 3 and 140,388,417.3333 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 2 210,582,626 421,165,252

Let's try dividing by 4.

421,165,252 ÷ 4 = 105,291,313

If the quotient is a whole number, then 4 and 105,291,313 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 4 105,291,313 210,582,626 421,165,252

We keep dividing by the next largest number, in this case the number 5. If the quotient of 421,165,252 ÷ 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:
