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 204,330,103, 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 | 204,330,103 | |
| -1 | -204,330,103 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 204,330,103.
Example:
1 x 204,330,103 = 204,330,103
and
-1 x -204,330,103 = 204,330,103
Notice both answers equal 204,330,103
With that explanation out of the way, let's continue. Next, we take the number 204,330,103 and divide it by 2:
204,330,103 ÷ 2 = 102,165,051.5
If the quotient is a whole number, then 2 and 102,165,051.5 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 | 204,330,103 | |
| -1 | -204,330,103 |
Now, we try dividing 204,330,103 by 3:
204,330,103 ÷ 3 = 68,110,034.3333
If the quotient is a whole number, then 3 and 68,110,034.3333 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 | 204,330,103 | |
| -1 | -204,330,103 |
Let's try dividing by 4:
204,330,103 ÷ 4 = 51,082,525.75
If the quotient is a whole number, then 4 and 51,082,525.75 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 | 204,330,103 | |
| -1 | 204,330,103 |
If you did it right, you will end up with this table:
| 1 | 47 | 79 | 113 | 487 | 3,713 | 5,311 | 8,927 | 22,889 | 38,473 | 55,031 | 419,569 | 1,808,231 | 2,586,457 | 4,347,449 | 204,330,103 |
| -1 | -47 | -79 | -113 | -487 | -3,713 | -5,311 | -8,927 | -22,889 | -38,473 | -55,031 | -419,569 | -1,808,231 | -2,586,457 | -4,347,449 | -204,330,103 |
