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 305,330,135, 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 | 305,330,135 | |
| -1 | -305,330,135 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 305,330,135.
Example:
1 x 305,330,135 = 305,330,135
and
-1 x -305,330,135 = 305,330,135
Notice both answers equal 305,330,135
With that explanation out of the way, let's continue. Next, we take the number 305,330,135 and divide it by 2:
305,330,135 ÷ 2 = 152,665,067.5
If the quotient is a whole number, then 2 and 152,665,067.5 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 | 305,330,135 | |
| -1 | -305,330,135 |
Now, we try dividing 305,330,135 by 3:
305,330,135 ÷ 3 = 101,776,711.6667
If the quotient is a whole number, then 3 and 101,776,711.6667 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 | 305,330,135 | |
| -1 | -305,330,135 |
Let's try dividing by 4:
305,330,135 ÷ 4 = 76,332,533.75
If the quotient is a whole number, then 4 and 76,332,533.75 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 | 305,330,135 | |
| -1 | 305,330,135 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 55 | 257 | 1,285 | 2,827 | 14,135 | 21,601 | 108,005 | 237,611 | 1,188,055 | 5,551,457 | 27,757,285 | 61,066,027 | 305,330,135 |
| -1 | -5 | -11 | -55 | -257 | -1,285 | -2,827 | -14,135 | -21,601 | -108,005 | -237,611 | -1,188,055 | -5,551,457 | -27,757,285 | -61,066,027 | -305,330,135 |
