How do I find the factor combinations of the number 224,404,415?

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 224,404,415, 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.

1 224,404,415
-1 -224,404,415

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 224,404,415.

Example:
1 x 224,404,415 = 224,404,415
and
-1 x -224,404,415 = 224,404,415
Notice both answers equal 224,404,415

With that explanation out of the way, let's continue. Next, we take the number 224,404,415 and divide it by 2:

224,404,415 ÷ 2 = 112,202,207.5

If the quotient is a whole number, then 2 and 112,202,207.5 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:

1 224,404,415
-1 -224,404,415

Now, we try dividing 224,404,415 by 3:

224,404,415 ÷ 3 = 74,801,471.6667

If the quotient is a whole number, then 3 and 74,801,471.6667 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:

1 224,404,415
-1 -224,404,415

Let's try dividing by 4:

224,404,415 ÷ 4 = 56,101,103.75

If the quotient is a whole number, then 4 and 56,101,103.75 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:

1 224,404,415
-1 224,404,415
Keep dividing by the next highest number until you cannot divide anymore.

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

154332,165103,651518,25544,880,883224,404,415
