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 204,331,415, 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 | 204,331,415 | |
| -1 | -204,331,415 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 204,331,415.
Example:
1 x 204,331,415 = 204,331,415
and
-1 x -204,331,415 = 204,331,415
Notice both answers equal 204,331,415
With that explanation out of the way, let's continue. Next, we take the number 204,331,415 and divide it by 2:
204,331,415 ÷ 2 = 102,165,707.5
If the quotient is a whole number, then 2 and 102,165,707.5 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 | 204,331,415 | |
| -1 | -204,331,415 |
Now, we try dividing 204,331,415 by 3:
204,331,415 ÷ 3 = 68,110,471.6667
If the quotient is a whole number, then 3 and 68,110,471.6667 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 | 204,331,415 | |
| -1 | -204,331,415 |
Let's try dividing by 4:
204,331,415 ÷ 4 = 51,082,853.75
If the quotient is a whole number, then 4 and 51,082,853.75 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 | 204,331,415 | |
| -1 | 204,331,415 |
If you did it right, you will end up with this table:
| 1 | 5 | 17 | 19 | 85 | 95 | 323 | 361 | 1,615 | 1,805 | 6,137 | 6,659 | 30,685 | 33,295 | 113,203 | 126,521 | 566,015 | 632,605 | 2,150,857 | 2,403,899 | 10,754,285 | 12,019,495 | 40,866,283 | 204,331,415 |
| -1 | -5 | -17 | -19 | -85 | -95 | -323 | -361 | -1,615 | -1,805 | -6,137 | -6,659 | -30,685 | -33,295 | -113,203 | -126,521 | -566,015 | -632,605 | -2,150,857 | -2,403,899 | -10,754,285 | -12,019,495 | -40,866,283 | -204,331,415 |
