How do I find the factors or divisors of the number 401,315,498?

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 401,315,498, 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.

1 401,315,498

Next, we take the number 401,315,498 and divide it by 2.

In this case, 401,315,498 ÷ 2 = 200,657,749

If the quotient is a whole number, then 2 and 200,657,749 are factors. Write them in the table below. If the quotient is not a whole number, skip to the next test.

1 2 200,657,749 401,315,498

Now, we try dividing 401,315,498 by 3.

401,315,498 ÷ 3 = 133,771,832.6667

If the quotient is a whole number, then 3 and 133,771,832.6667 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 2 200,657,749 401,315,498

Let's try dividing by 4.

401,315,498 ÷ 4 = 100,328,874.5

If the quotient is a whole number, then 4 and 100,328,874.5 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 2 200,657,749 401,315,498

We keep dividing by the next largest number, in this case the number 5. If the quotient of 401,315,498 ÷ 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:

12173411,803,39723,606,794200,657,749401,315,498
