How do I find the factor combinations of the number 22,104,203?

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 22,104,203, 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 22,104,203
-1 -22,104,203

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 22,104,203.

Example:
1 x 22,104,203 = 22,104,203
and
-1 x -22,104,203 = 22,104,203
Notice both answers equal 22,104,203

With that explanation out of the way, let's continue. Next, we take the number 22,104,203 and divide it by 2:

22,104,203 ÷ 2 = 11,052,101.5

If the quotient is a whole number, then 2 and 11,052,101.5 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 22,104,203
-1 -22,104,203

Now, we try dividing 22,104,203 by 3:

22,104,203 ÷ 3 = 7,368,067.6667

If the quotient is a whole number, then 3 and 7,368,067.6667 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 22,104,203
-1 -22,104,203

Let's try dividing by 4:

22,104,203 ÷ 4 = 5,526,050.75

If the quotient is a whole number, then 4 and 5,526,050.75 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 22,104,203
-1 22,104,203
Keep dividing by the next highest number until you cannot divide anymore.

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

1114994,0275,48944,2972,009,47322,104,203
-1-11-499-4,027-5,489-44,297-2,009,473-22,104,203
