How do I find the factor combinations of the number 204,261,512?

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 204,261,512, 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.

1 204,261,512
-1 -204,261,512

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 204,261,512.

Example:
1 x 204,261,512 = 204,261,512
and
-1 x -204,261,512 = 204,261,512
Notice both answers equal 204,261,512

With that explanation out of the way, let's continue. Next, we take the number 204,261,512 and divide it by 2:

204,261,512 ÷ 2 = 102,130,756

If the quotient is a whole number, then 2 and 102,130,756 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 2 102,130,756 204,261,512
-1 -2 -102,130,756 -204,261,512

Now, we try dividing 204,261,512 by 3:

204,261,512 ÷ 3 = 68,087,170.6667

If the quotient is a whole number, then 3 and 68,087,170.6667 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 2 102,130,756 204,261,512
-1 -2 -102,130,756 -204,261,512

Let's try dividing by 4:

204,261,512 ÷ 4 = 51,065,378

If the quotient is a whole number, then 4 and 51,065,378 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 51,065,378 102,130,756 204,261,512
-1 -2 -4 -51,065,378 -102,130,756 204,261,512
Keep dividing by the next highest number until you cannot divide anymore.

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