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 321,331,127, 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 | 321,331,127 | |
| -1 | -321,331,127 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 321,331,127.
Example:
1 x 321,331,127 = 321,331,127
and
-1 x -321,331,127 = 321,331,127
Notice both answers equal 321,331,127
With that explanation out of the way, let's continue. Next, we take the number 321,331,127 and divide it by 2:
321,331,127 ÷ 2 = 160,665,563.5
If the quotient is a whole number, then 2 and 160,665,563.5 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 | 321,331,127 | |
| -1 | -321,331,127 |
Now, we try dividing 321,331,127 by 3:
321,331,127 ÷ 3 = 107,110,375.6667
If the quotient is a whole number, then 3 and 107,110,375.6667 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 | 321,331,127 | |
| -1 | -321,331,127 |
Let's try dividing by 4:
321,331,127 ÷ 4 = 80,332,781.75
If the quotient is a whole number, then 4 and 80,332,781.75 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 | 321,331,127 | |
| -1 | 321,331,127 |
If you did it right, you will end up with this table:
| 1 | 13 | 17 | 221 | 839 | 1,733 | 10,907 | 14,263 | 22,529 | 29,461 | 185,419 | 382,993 | 1,453,987 | 18,901,831 | 24,717,779 | 321,331,127 |
| -1 | -13 | -17 | -221 | -839 | -1,733 | -10,907 | -14,263 | -22,529 | -29,461 | -185,419 | -382,993 | -1,453,987 | -18,901,831 | -24,717,779 | -321,331,127 |
