How do I find the factor combinations of the number 251,377,368?

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 251,377,368, 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.

1 251,377,368
-1 -251,377,368

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 251,377,368.

Example:
1 x 251,377,368 = 251,377,368
and
-1 x -251,377,368 = 251,377,368
Notice both answers equal 251,377,368

With that explanation out of the way, let's continue. Next, we take the number 251,377,368 and divide it by 2:

251,377,368 ÷ 2 = 125,688,684

If the quotient is a whole number, then 2 and 125,688,684 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 2 125,688,684 251,377,368
-1 -2 -125,688,684 -251,377,368

Now, we try dividing 251,377,368 by 3:

251,377,368 ÷ 3 = 83,792,456

If the quotient is a whole number, then 3 and 83,792,456 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 83,792,456 125,688,684 251,377,368
-1 -2 -3 -83,792,456 -125,688,684 -251,377,368

Let's try dividing by 4:

251,377,368 ÷ 4 = 62,844,342

If the quotient is a whole number, then 4 and 62,844,342 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 62,844,342 83,792,456 125,688,684 251,377,368
-1 -2 -3 -4 -62,844,342 -83,792,456 -125,688,684 251,377,368
Keep dividing by the next highest number until you cannot divide anymore.

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