How do I find the factors or divisors of the number 401,622,636?

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 401,622,636, 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.

1 401,622,636

Next, we take the number 401,622,636 and divide it by 2.

In this case, 401,622,636 ÷ 2 = 200,811,318

If the quotient is a whole number, then 2 and 200,811,318 are factors. Write them in the table below. If the quotient is not a whole number, skip to the next test.

1 2 200,811,318 401,622,636

Now, we try dividing 401,622,636 by 3.

401,622,636 ÷ 3 = 133,874,212

If the quotient is a whole number, then 3 and 133,874,212 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 3 133,874,212 200,811,318 401,622,636

Let's try dividing by 4.

401,622,636 ÷ 4 = 100,405,659

If the quotient is a whole number, then 4 and 100,405,659 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 4 100,405,659 133,874,212 200,811,318 401,622,636

We keep dividing by the next largest number, in this case the number 5. If the quotient of 401,622,636 ÷ 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:
