How do I find the factor combinations of the number 404,161,332?

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 divisors of larger numbers. To find the factor combinations of the number 404,161,332, it is easier to work with a table - it's called factoring from the outside in.

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. Then, below that, write the numbers as a negative as well.

1 404,161,332
-1 -404,161,332

Why are the negative numbers included?

When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 404,161,332.

Example:
1 x 404,161,332 = 404,161,332
and
-1 x -404,161,332 = 404,161,332
Notice both answers equal 404,161,332

With that explanation out of the way, let's continue. Next, we take the number 404,161,332 and divide it by 2:

404,161,332 ÷ 2 = 202,080,666

If the quotient is a whole number, then 2 and 202,080,666 are factors. In this case, the quotient is a whole number. Write them in the table inside the other two factors like the below example. Don't forget to write the negative numbers too!

Here is what our table should look like at this step:

1 2 202,080,666 404,161,332
-1 -2 -202,080,666 -404,161,332

Now, we try dividing 404,161,332 by 3:

404,161,332 ÷ 3 = 134,720,444

If the quotient is a whole number, then 3 and 134,720,444 are factors. In this case, the quotient is a whole number. Write them in the table inside the other two factors like the below example. Don't forget to write the negative numbers too!

Here is what our table should look like at this step:

1 2 3 134,720,444 202,080,666 404,161,332
-1 -2 -3 -134,720,444 -202,080,666 -404,161,332

Let's try dividing by 4:

404,161,332 ÷ 4 = 101,040,333

If the quotient is a whole number, then 4 and 101,040,333 are factors. In this case, the quotient is a whole number. Write them in the table inside the other two factors like the below example. Don't forget to write the negative numbers too!

Here is what our table should look like at this step:

1 2 3 4 101,040,333 134,720,444 202,080,666 404,161,332
-1 -2 -3 -4 -101,040,333 -134,720,444 -202,080,666 404,161,332
Keep dividing by the next highest number until you cannot divide anymore.

If you did it right, you will end up with this table:
