How do I find the factor combinations of the number 644,106,204?

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 644,106,204, 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.

1 644,106,204
-1 -644,106,204

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 644,106,204.

Example:
1 x 644,106,204 = 644,106,204
and
-1 x -644,106,204 = 644,106,204
Notice both answers equal 644,106,204

With that explanation out of the way, let's continue. Next, we take the number 644,106,204 and divide it by 2:

644,106,204 ÷ 2 = 322,053,102

If the quotient is a whole number, then 2 and 322,053,102 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 2 322,053,102 644,106,204
-1 -2 -322,053,102 -644,106,204

Now, we try dividing 644,106,204 by 3:

644,106,204 ÷ 3 = 214,702,068

If the quotient is a whole number, then 3 and 214,702,068 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 3 214,702,068 322,053,102 644,106,204
-1 -2 -3 -214,702,068 -322,053,102 -644,106,204

Let's try dividing by 4:

644,106,204 ÷ 4 = 161,026,551

If the quotient is a whole number, then 4 and 161,026,551 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 4 161,026,551 214,702,068 322,053,102 644,106,204
-1 -2 -3 -4 -161,026,551 -214,702,068 -322,053,102 644,106,204
Keep dividing by the next highest number until you cannot divide anymore.

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