How do I find the factors or divisors of the number 400,511,028?

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 400,511,028, 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.

1 400,511,028

Next, we take the number 400,511,028 and divide it by 2.

In this case, 400,511,028 ÷ 2 = 200,255,514

If the quotient is a whole number, then 2 and 200,255,514 are factors. Write them in the table below. If the quotient is not a whole number, skip to the next test.

1 2 200,255,514 400,511,028

Now, we try dividing 400,511,028 by 3.

400,511,028 ÷ 3 = 133,503,676

If the quotient is a whole number, then 3 and 133,503,676 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 3 133,503,676 200,255,514 400,511,028

Let's try dividing by 4.

400,511,028 ÷ 4 = 100,127,757

If the quotient is a whole number, then 4 and 100,127,757 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 4 100,127,757 133,503,676 200,255,514 400,511,028

We keep dividing by the next largest number, in this case the number 5. If the quotient of 400,511,028 ÷ 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:
