How do I find the factor combinations of the number 254,521,488?

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 254,521,488, 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.

1 254,521,488
-1 -254,521,488

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 254,521,488.

Example:
1 x 254,521,488 = 254,521,488
and
-1 x -254,521,488 = 254,521,488
Notice both answers equal 254,521,488

With that explanation out of the way, let's continue. Next, we take the number 254,521,488 and divide it by 2:

254,521,488 ÷ 2 = 127,260,744

If the quotient is a whole number, then 2 and 127,260,744 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 2 127,260,744 254,521,488
-1 -2 -127,260,744 -254,521,488

Now, we try dividing 254,521,488 by 3:

254,521,488 ÷ 3 = 84,840,496

If the quotient is a whole number, then 3 and 84,840,496 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 84,840,496 127,260,744 254,521,488
-1 -2 -3 -84,840,496 -127,260,744 -254,521,488

Let's try dividing by 4:

254,521,488 ÷ 4 = 63,630,372

If the quotient is a whole number, then 4 and 63,630,372 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 63,630,372 84,840,496 127,260,744 254,521,488
-1 -2 -3 -4 -63,630,372 -84,840,496 -127,260,744 254,521,488
Keep dividing by the next highest number until you cannot divide anymore.

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