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 331,134,335, 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 | 331,134,335 | |
| -1 | -331,134,335 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 331,134,335.
Example:
1 x 331,134,335 = 331,134,335
and
-1 x -331,134,335 = 331,134,335
Notice both answers equal 331,134,335
With that explanation out of the way, let's continue. Next, we take the number 331,134,335 and divide it by 2:
331,134,335 ÷ 2 = 165,567,167.5
If the quotient is a whole number, then 2 and 165,567,167.5 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 | 331,134,335 | |
| -1 | -331,134,335 |
Now, we try dividing 331,134,335 by 3:
331,134,335 ÷ 3 = 110,378,111.6667
If the quotient is a whole number, then 3 and 110,378,111.6667 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 | 331,134,335 | |
| -1 | -331,134,335 |
Let's try dividing by 4:
331,134,335 ÷ 4 = 82,783,583.75
If the quotient is a whole number, then 4 and 82,783,583.75 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 | 331,134,335 | |
| -1 | 331,134,335 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 23 | 35 | 115 | 161 | 805 | 411,347 | 2,056,735 | 2,879,429 | 9,460,981 | 14,397,145 | 47,304,905 | 66,226,867 | 331,134,335 |
| -1 | -5 | -7 | -23 | -35 | -115 | -161 | -805 | -411,347 | -2,056,735 | -2,879,429 | -9,460,981 | -14,397,145 | -47,304,905 | -66,226,867 | -331,134,335 |
