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 204,112,327, 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 | 204,112,327 | |
| -1 | -204,112,327 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 204,112,327.
Example:
1 x 204,112,327 = 204,112,327
and
-1 x -204,112,327 = 204,112,327
Notice both answers equal 204,112,327
With that explanation out of the way, let's continue. Next, we take the number 204,112,327 and divide it by 2:
204,112,327 ÷ 2 = 102,056,163.5
If the quotient is a whole number, then 2 and 102,056,163.5 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 | 204,112,327 | |
| -1 | -204,112,327 |
Now, we try dividing 204,112,327 by 3:
204,112,327 ÷ 3 = 68,037,442.3333
If the quotient is a whole number, then 3 and 68,037,442.3333 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 | 204,112,327 | |
| -1 | -204,112,327 |
Let's try dividing by 4:
204,112,327 ÷ 4 = 51,028,081.75
If the quotient is a whole number, then 4 and 51,028,081.75 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 | 204,112,327 | |
| -1 | 204,112,327 |
If you did it right, you will end up with this table:
| 1 | 23 | 137 | 211 | 307 | 3,151 | 4,853 | 7,061 | 28,907 | 42,059 | 64,777 | 664,861 | 967,357 | 1,489,871 | 8,874,449 | 204,112,327 |
| -1 | -23 | -137 | -211 | -307 | -3,151 | -4,853 | -7,061 | -28,907 | -42,059 | -64,777 | -664,861 | -967,357 | -1,489,871 | -8,874,449 | -204,112,327 |
