How do I find the factor combinations of the number 247,722,252?

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 247,722,252, 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.

1 247,722,252
-1 -247,722,252

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 247,722,252.

Example:
1 x 247,722,252 = 247,722,252
and
-1 x -247,722,252 = 247,722,252
Notice both answers equal 247,722,252

With that explanation out of the way, let's continue. Next, we take the number 247,722,252 and divide it by 2:

247,722,252 ÷ 2 = 123,861,126

If the quotient is a whole number, then 2 and 123,861,126 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 2 123,861,126 247,722,252
-1 -2 -123,861,126 -247,722,252

Now, we try dividing 247,722,252 by 3:

247,722,252 ÷ 3 = 82,574,084

If the quotient is a whole number, then 3 and 82,574,084 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 82,574,084 123,861,126 247,722,252
-1 -2 -3 -82,574,084 -123,861,126 -247,722,252

Let's try dividing by 4:

247,722,252 ÷ 4 = 61,930,563

If the quotient is a whole number, then 4 and 61,930,563 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 61,930,563 82,574,084 123,861,126 247,722,252
-1 -2 -3 -4 -61,930,563 -82,574,084 -123,861,126 247,722,252
Keep dividing by the next highest number until you cannot divide anymore.

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