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 204,230,663, 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 | 204,230,663 | |
| -1 | -204,230,663 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 204,230,663.
Example:
1 x 204,230,663 = 204,230,663
and
-1 x -204,230,663 = 204,230,663
Notice both answers equal 204,230,663
With that explanation out of the way, let's continue. Next, we take the number 204,230,663 and divide it by 2:
204,230,663 ÷ 2 = 102,115,331.5
If the quotient is a whole number, then 2 and 102,115,331.5 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 | 204,230,663 | |
| -1 | -204,230,663 |
Now, we try dividing 204,230,663 by 3:
204,230,663 ÷ 3 = 68,076,887.6667
If the quotient is a whole number, then 3 and 68,076,887.6667 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 | 204,230,663 | |
| -1 | -204,230,663 |
Let's try dividing by 4:
204,230,663 ÷ 4 = 51,057,665.75
If the quotient is a whole number, then 4 and 51,057,665.75 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 | 204,230,663 | |
| -1 | 204,230,663 |
If you did it right, you will end up with this table:
| 1 | 7 | 13 | 91 | 113 | 791 | 1,469 | 10,283 | 19,861 | 139,027 | 258,193 | 1,807,351 | 2,244,293 | 15,710,051 | 29,175,809 | 204,230,663 |
| -1 | -7 | -13 | -91 | -113 | -791 | -1,469 | -10,283 | -19,861 | -139,027 | -258,193 | -1,807,351 | -2,244,293 | -15,710,051 | -29,175,809 | -204,230,663 |
