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 204,604,009, 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 | 204,604,009 | |
| -1 | -204,604,009 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 204,604,009.
Example:
1 x 204,604,009 = 204,604,009
and
-1 x -204,604,009 = 204,604,009
Notice both answers equal 204,604,009
With that explanation out of the way, let's continue. Next, we take the number 204,604,009 and divide it by 2:
204,604,009 ÷ 2 = 102,302,004.5
If the quotient is a whole number, then 2 and 102,302,004.5 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 | 204,604,009 | |
| -1 | -204,604,009 |
Now, we try dividing 204,604,009 by 3:
204,604,009 ÷ 3 = 68,201,336.3333
If the quotient is a whole number, then 3 and 68,201,336.3333 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 | 204,604,009 | |
| -1 | -204,604,009 |
Let's try dividing by 4:
204,604,009 ÷ 4 = 51,151,002.25
If the quotient is a whole number, then 4 and 51,151,002.25 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 | 204,604,009 | |
| -1 | 204,604,009 |
If you did it right, you will end up with this table:
| 1 | 53 | 107 | 109 | 331 | 5,671 | 5,777 | 11,663 | 17,543 | 35,417 | 36,079 | 618,139 | 1,877,101 | 1,912,187 | 3,860,453 | 204,604,009 |
| -1 | -53 | -107 | -109 | -331 | -5,671 | -5,777 | -11,663 | -17,543 | -35,417 | -36,079 | -618,139 | -1,877,101 | -1,912,187 | -3,860,453 | -204,604,009 |
