How do I find the factor combinations of the number 671,432,664?

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 671,432,664, 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.

1 671,432,664
-1 -671,432,664

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 671,432,664.

Example:
1 x 671,432,664 = 671,432,664
and
-1 x -671,432,664 = 671,432,664
Notice both answers equal 671,432,664

With that explanation out of the way, let's continue. Next, we take the number 671,432,664 and divide it by 2:

671,432,664 ÷ 2 = 335,716,332

If the quotient is a whole number, then 2 and 335,716,332 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 2 335,716,332 671,432,664
-1 -2 -335,716,332 -671,432,664

Now, we try dividing 671,432,664 by 3:

671,432,664 ÷ 3 = 223,810,888

If the quotient is a whole number, then 3 and 223,810,888 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 3 223,810,888 335,716,332 671,432,664
-1 -2 -3 -223,810,888 -335,716,332 -671,432,664

Let's try dividing by 4:

671,432,664 ÷ 4 = 167,858,166

If the quotient is a whole number, then 4 and 167,858,166 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 4 167,858,166 223,810,888 335,716,332 671,432,664
-1 -2 -3 -4 -167,858,166 -223,810,888 -335,716,332 671,432,664
Keep dividing by the next highest number until you cannot divide anymore.

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