How do I find the factor combinations of the number 611,012,664?

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 611,012,664, 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.

1 611,012,664
-1 -611,012,664

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 611,012,664.

Example:
1 x 611,012,664 = 611,012,664
and
-1 x -611,012,664 = 611,012,664
Notice both answers equal 611,012,664

With that explanation out of the way, let's continue. Next, we take the number 611,012,664 and divide it by 2:

611,012,664 ÷ 2 = 305,506,332

If the quotient is a whole number, then 2 and 305,506,332 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 2 305,506,332 611,012,664
-1 -2 -305,506,332 -611,012,664

Now, we try dividing 611,012,664 by 3:

611,012,664 ÷ 3 = 203,670,888

If the quotient is a whole number, then 3 and 203,670,888 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 3 203,670,888 305,506,332 611,012,664
-1 -2 -3 -203,670,888 -305,506,332 -611,012,664

Let's try dividing by 4:

611,012,664 ÷ 4 = 152,753,166

If the quotient is a whole number, then 4 and 152,753,166 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 4 152,753,166 203,670,888 305,506,332 611,012,664
-1 -2 -3 -4 -152,753,166 -203,670,888 -305,506,332 611,012,664
Keep dividing by the next highest number until you cannot divide anymore.

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