How do I find the factor combinations of the number 644,430,752?

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 644,430,752, 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.

1 644,430,752
-1 -644,430,752

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 644,430,752.

Example:
1 x 644,430,752 = 644,430,752
and
-1 x -644,430,752 = 644,430,752
Notice both answers equal 644,430,752

With that explanation out of the way, let's continue. Next, we take the number 644,430,752 and divide it by 2:

644,430,752 ÷ 2 = 322,215,376

If the quotient is a whole number, then 2 and 322,215,376 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 2 322,215,376 644,430,752
-1 -2 -322,215,376 -644,430,752

Now, we try dividing 644,430,752 by 3:

644,430,752 ÷ 3 = 214,810,250.6667

If the quotient is a whole number, then 3 and 214,810,250.6667 are factors. In this case, the quotient is not a whole number. Don't write anything down and try the next divisor.

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

1 2 322,215,376 644,430,752
-1 -2 -322,215,376 -644,430,752

Let's try dividing by 4:

644,430,752 ÷ 4 = 161,107,688

If the quotient is a whole number, then 4 and 161,107,688 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 4 161,107,688 322,215,376 644,430,752
-1 -2 -4 -161,107,688 -322,215,376 644,430,752
Keep dividing by the next highest number until you cannot divide anymore.

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