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 204,221,303, 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 | 204,221,303 | |
| -1 | -204,221,303 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 204,221,303.
Example:
1 x 204,221,303 = 204,221,303
and
-1 x -204,221,303 = 204,221,303
Notice both answers equal 204,221,303
With that explanation out of the way, let's continue. Next, we take the number 204,221,303 and divide it by 2:
204,221,303 ÷ 2 = 102,110,651.5
If the quotient is a whole number, then 2 and 102,110,651.5 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 | 204,221,303 | |
| -1 | -204,221,303 |
Now, we try dividing 204,221,303 by 3:
204,221,303 ÷ 3 = 68,073,767.6667
If the quotient is a whole number, then 3 and 68,073,767.6667 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 | 204,221,303 | |
| -1 | -204,221,303 |
Let's try dividing by 4:
204,221,303 ÷ 4 = 51,055,325.75
If the quotient is a whole number, then 4 and 51,055,325.75 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 | 204,221,303 | |
| -1 | 204,221,303 |
If you did it right, you will end up with this table:
| 1 | 11 | 13 | 143 | 269 | 2,959 | 3,497 | 5,309 | 38,467 | 58,399 | 69,017 | 759,187 | 1,428,121 | 15,709,331 | 18,565,573 | 204,221,303 |
| -1 | -11 | -13 | -143 | -269 | -2,959 | -3,497 | -5,309 | -38,467 | -58,399 | -69,017 | -759,187 | -1,428,121 | -15,709,331 | -18,565,573 | -204,221,303 |
