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 204,601,655, 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 | 204,601,655 | |
| -1 | -204,601,655 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 204,601,655.
Example:
1 x 204,601,655 = 204,601,655
and
-1 x -204,601,655 = 204,601,655
Notice both answers equal 204,601,655
With that explanation out of the way, let's continue. Next, we take the number 204,601,655 and divide it by 2:
204,601,655 ÷ 2 = 102,300,827.5
If the quotient is a whole number, then 2 and 102,300,827.5 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 | 204,601,655 | |
| -1 | -204,601,655 |
Now, we try dividing 204,601,655 by 3:
204,601,655 ÷ 3 = 68,200,551.6667
If the quotient is a whole number, then 3 and 68,200,551.6667 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 | 204,601,655 | |
| -1 | -204,601,655 |
Let's try dividing by 4:
204,601,655 ÷ 4 = 51,150,413.75
If the quotient is a whole number, then 4 and 51,150,413.75 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 | 204,601,655 | |
| -1 | 204,601,655 |
If you did it right, you will end up with this table:
| 1 | 5 | 89 | 107 | 445 | 535 | 4,297 | 9,523 | 21,485 | 47,615 | 382,433 | 459,779 | 1,912,165 | 2,298,895 | 40,920,331 | 204,601,655 |
| -1 | -5 | -89 | -107 | -445 | -535 | -4,297 | -9,523 | -21,485 | -47,615 | -382,433 | -459,779 | -1,912,165 | -2,298,895 | -40,920,331 | -204,601,655 |
