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 204,603,125, 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 | 204,603,125 | |
| -1 | -204,603,125 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 204,603,125.
Example:
1 x 204,603,125 = 204,603,125
and
-1 x -204,603,125 = 204,603,125
Notice both answers equal 204,603,125
With that explanation out of the way, let's continue. Next, we take the number 204,603,125 and divide it by 2:
204,603,125 ÷ 2 = 102,301,562.5
If the quotient is a whole number, then 2 and 102,301,562.5 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 | 204,603,125 | |
| -1 | -204,603,125 |
Now, we try dividing 204,603,125 by 3:
204,603,125 ÷ 3 = 68,201,041.6667
If the quotient is a whole number, then 3 and 68,201,041.6667 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 | 204,603,125 | |
| -1 | -204,603,125 |
Let's try dividing by 4:
204,603,125 ÷ 4 = 51,150,781.25
If the quotient is a whole number, then 4 and 51,150,781.25 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 | 204,603,125 | |
| -1 | 204,603,125 |
If you did it right, you will end up with this table:
| 1 | 5 | 25 | 125 | 233 | 281 | 625 | 1,165 | 1,405 | 3,125 | 5,825 | 7,025 | 29,125 | 35,125 | 65,473 | 145,625 | 175,625 | 327,365 | 728,125 | 878,125 | 1,636,825 | 8,184,125 | 40,920,625 | 204,603,125 |
| -1 | -5 | -25 | -125 | -233 | -281 | -625 | -1,165 | -1,405 | -3,125 | -5,825 | -7,025 | -29,125 | -35,125 | -65,473 | -145,625 | -175,625 | -327,365 | -728,125 | -878,125 | -1,636,825 | -8,184,125 | -40,920,625 | -204,603,125 |
