How do I find the factor combinations of the number 453,224,401?

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 453,224,401, 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.

1 453,224,401
-1 -453,224,401

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 453,224,401.

Example:
1 x 453,224,401 = 453,224,401
and
-1 x -453,224,401 = 453,224,401
Notice both answers equal 453,224,401

With that explanation out of the way, let's continue. Next, we take the number 453,224,401 and divide it by 2:

453,224,401 ÷ 2 = 226,612,200.5

If the quotient is a whole number, then 2 and 226,612,200.5 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:

1 453,224,401
-1 -453,224,401

Now, we try dividing 453,224,401 by 3:

453,224,401 ÷ 3 = 151,074,800.3333

If the quotient is a whole number, then 3 and 151,074,800.3333 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:

1 453,224,401
-1 -453,224,401

Let's try dividing by 4:

453,224,401 ÷ 4 = 113,306,100.25

If the quotient is a whole number, then 4 and 113,306,100.25 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:

1 453,224,401
-1 453,224,401
Keep dividing by the next highest number until you cannot divide anymore.

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

1789623727,4875,092,40964,746,343453,224,401
-1-7-89-623-727,487-5,092,409-64,746,343-453,224,401
