How do I find the factor combinations of the number 211,012,008?

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 211,012,008, 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.

1 211,012,008
-1 -211,012,008

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 211,012,008.

Example:
1 x 211,012,008 = 211,012,008
and
-1 x -211,012,008 = 211,012,008
Notice both answers equal 211,012,008

With that explanation out of the way, let's continue. Next, we take the number 211,012,008 and divide it by 2:

211,012,008 ÷ 2 = 105,506,004

If the quotient is a whole number, then 2 and 105,506,004 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 2 105,506,004 211,012,008
-1 -2 -105,506,004 -211,012,008

Now, we try dividing 211,012,008 by 3:

211,012,008 ÷ 3 = 70,337,336

If the quotient is a whole number, then 3 and 70,337,336 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 70,337,336 105,506,004 211,012,008
-1 -2 -3 -70,337,336 -105,506,004 -211,012,008

Let's try dividing by 4:

211,012,008 ÷ 4 = 52,753,002

If the quotient is a whole number, then 4 and 52,753,002 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 52,753,002 70,337,336 105,506,004 211,012,008
-1 -2 -3 -4 -52,753,002 -70,337,336 -105,506,004 211,012,008
Keep dividing by the next highest number until you cannot divide anymore.

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