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 204,201,305, 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 | 204,201,305 | |
| -1 | -204,201,305 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 204,201,305.
Example:
1 x 204,201,305 = 204,201,305
and
-1 x -204,201,305 = 204,201,305
Notice both answers equal 204,201,305
With that explanation out of the way, let's continue. Next, we take the number 204,201,305 and divide it by 2:
204,201,305 ÷ 2 = 102,100,652.5
If the quotient is a whole number, then 2 and 102,100,652.5 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 | 204,201,305 | |
| -1 | -204,201,305 |
Now, we try dividing 204,201,305 by 3:
204,201,305 ÷ 3 = 68,067,101.6667
If the quotient is a whole number, then 3 and 68,067,101.6667 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 | 204,201,305 | |
| -1 | -204,201,305 |
Let's try dividing by 4:
204,201,305 ÷ 4 = 51,050,326.25
If the quotient is a whole number, then 4 and 51,050,326.25 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 | 204,201,305 | |
| -1 | 204,201,305 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 11 | 35 | 55 | 77 | 385 | 530,393 | 2,651,965 | 3,712,751 | 5,834,323 | 18,563,755 | 29,171,615 | 40,840,261 | 204,201,305 |
| -1 | -5 | -7 | -11 | -35 | -55 | -77 | -385 | -530,393 | -2,651,965 | -3,712,751 | -5,834,323 | -18,563,755 | -29,171,615 | -40,840,261 | -204,201,305 |
