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 204,232,625, 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 | 204,232,625 | |
| -1 | -204,232,625 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 204,232,625.
Example:
1 x 204,232,625 = 204,232,625
and
-1 x -204,232,625 = 204,232,625
Notice both answers equal 204,232,625
With that explanation out of the way, let's continue. Next, we take the number 204,232,625 and divide it by 2:
204,232,625 ÷ 2 = 102,116,312.5
If the quotient is a whole number, then 2 and 102,116,312.5 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 | 204,232,625 | |
| -1 | -204,232,625 |
Now, we try dividing 204,232,625 by 3:
204,232,625 ÷ 3 = 68,077,541.6667
If the quotient is a whole number, then 3 and 68,077,541.6667 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 | 204,232,625 | |
| -1 | -204,232,625 |
Let's try dividing by 4:
204,232,625 ÷ 4 = 51,058,156.25
If the quotient is a whole number, then 4 and 51,058,156.25 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 | 204,232,625 | |
| -1 | 204,232,625 |
If you did it right, you will end up with this table:
| 1 | 5 | 25 | 47 | 125 | 235 | 1,175 | 5,875 | 34,763 | 173,815 | 869,075 | 1,633,861 | 4,345,375 | 8,169,305 | 40,846,525 | 204,232,625 |
| -1 | -5 | -25 | -47 | -125 | -235 | -1,175 | -5,875 | -34,763 | -173,815 | -869,075 | -1,633,861 | -4,345,375 | -8,169,305 | -40,846,525 | -204,232,625 |
