How do I find the factor combinations of the number 550,413,144?

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 550,413,144, 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.

1 550,413,144
-1 -550,413,144

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 550,413,144.

Example:
1 x 550,413,144 = 550,413,144
and
-1 x -550,413,144 = 550,413,144
Notice both answers equal 550,413,144

With that explanation out of the way, let's continue. Next, we take the number 550,413,144 and divide it by 2:

550,413,144 ÷ 2 = 275,206,572

If the quotient is a whole number, then 2 and 275,206,572 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 2 275,206,572 550,413,144
-1 -2 -275,206,572 -550,413,144

Now, we try dividing 550,413,144 by 3:

550,413,144 ÷ 3 = 183,471,048

If the quotient is a whole number, then 3 and 183,471,048 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 3 183,471,048 275,206,572 550,413,144
-1 -2 -3 -183,471,048 -275,206,572 -550,413,144

Let's try dividing by 4:

550,413,144 ÷ 4 = 137,603,286

If the quotient is a whole number, then 4 and 137,603,286 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 4 137,603,286 183,471,048 275,206,572 550,413,144
-1 -2 -3 -4 -137,603,286 -183,471,048 -275,206,572 550,413,144
Keep dividing by the next highest number until you cannot divide anymore.

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