How do I find the factor combinations of the number 223,160,303?

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 223,160,303, 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.

1 223,160,303
-1 -223,160,303

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 223,160,303.

Example:
1 x 223,160,303 = 223,160,303
and
-1 x -223,160,303 = 223,160,303
Notice both answers equal 223,160,303

With that explanation out of the way, let's continue. Next, we take the number 223,160,303 and divide it by 2:

223,160,303 ÷ 2 = 111,580,151.5

If the quotient is a whole number, then 2 and 111,580,151.5 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:

1 223,160,303
-1 -223,160,303

Now, we try dividing 223,160,303 by 3:

223,160,303 ÷ 3 = 74,386,767.6667

If the quotient is a whole number, then 3 and 74,386,767.6667 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:

1 223,160,303
-1 -223,160,303

Let's try dividing by 4:

223,160,303 ÷ 4 = 55,790,075.75

If the quotient is a whole number, then 4 and 55,790,075.75 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:

1 223,160,303
-1 223,160,303
Keep dividing by the next highest number until you cannot divide anymore.

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

11931,156,271223,160,303
-1-193-1,156,271-223,160,303
