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 204,252,305, 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 | 204,252,305 | |
| -1 | -204,252,305 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 204,252,305.
Example:
1 x 204,252,305 = 204,252,305
and
-1 x -204,252,305 = 204,252,305
Notice both answers equal 204,252,305
With that explanation out of the way, let's continue. Next, we take the number 204,252,305 and divide it by 2:
204,252,305 ÷ 2 = 102,126,152.5
If the quotient is a whole number, then 2 and 102,126,152.5 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 | 204,252,305 | |
| -1 | -204,252,305 |
Now, we try dividing 204,252,305 by 3:
204,252,305 ÷ 3 = 68,084,101.6667
If the quotient is a whole number, then 3 and 68,084,101.6667 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 | 204,252,305 | |
| -1 | -204,252,305 |
Let's try dividing by 4:
204,252,305 ÷ 4 = 51,063,076.25
If the quotient is a whole number, then 4 and 51,063,076.25 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 | 204,252,305 | |
| -1 | 204,252,305 |
If you did it right, you will end up with this table:
| 1 | 5 | 23 | 115 | 661 | 2,687 | 3,305 | 13,435 | 15,203 | 61,801 | 76,015 | 309,005 | 1,776,107 | 8,880,535 | 40,850,461 | 204,252,305 |
| -1 | -5 | -23 | -115 | -661 | -2,687 | -3,305 | -13,435 | -15,203 | -61,801 | -76,015 | -309,005 | -1,776,107 | -8,880,535 | -40,850,461 | -204,252,305 |
