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 223,300,321, it is easier to work with a table - it's called factoring from the outside in.
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 | 223,300,321 | |
| -1 | -223,300,321 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 223,300,321.
Example:
1 x 223,300,321 = 223,300,321
and
-1 x -223,300,321 = 223,300,321
Notice both answers equal 223,300,321
With that explanation out of the way, let's continue. Next, we take the number 223,300,321 and divide it by 2:
223,300,321 ÷ 2 = 111,650,160.5
If the quotient is a whole number, then 2 and 111,650,160.5 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 | 223,300,321 | |
| -1 | -223,300,321 |
Now, we try dividing 223,300,321 by 3:
223,300,321 ÷ 3 = 74,433,440.3333
If the quotient is a whole number, then 3 and 74,433,440.3333 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 | 223,300,321 | |
| -1 | -223,300,321 |
Let's try dividing by 4:
223,300,321 ÷ 4 = 55,825,080.25
If the quotient is a whole number, then 4 and 55,825,080.25 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 | 223,300,321 | |
| -1 | 223,300,321 |
If you did it right, you will end up with this table:
| 1 | 17 | 61 | 349 | 617 | 1,037 | 5,933 | 10,489 | 21,289 | 37,637 | 215,333 | 361,913 | 639,829 | 3,660,661 | 13,135,313 | 223,300,321 |
| -1 | -17 | -61 | -349 | -617 | -1,037 | -5,933 | -10,489 | -21,289 | -37,637 | -215,333 | -361,913 | -639,829 | -3,660,661 | -13,135,313 | -223,300,321 |
