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 331,302,239, 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 | 331,302,239 | |
| -1 | -331,302,239 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 331,302,239.
Example:
1 x 331,302,239 = 331,302,239
and
-1 x -331,302,239 = 331,302,239
Notice both answers equal 331,302,239
With that explanation out of the way, let's continue. Next, we take the number 331,302,239 and divide it by 2:
331,302,239 ÷ 2 = 165,651,119.5
If the quotient is a whole number, then 2 and 165,651,119.5 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 | 331,302,239 | |
| -1 | -331,302,239 |
Now, we try dividing 331,302,239 by 3:
331,302,239 ÷ 3 = 110,434,079.6667
If the quotient is a whole number, then 3 and 110,434,079.6667 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 | 331,302,239 | |
| -1 | -331,302,239 |
Let's try dividing by 4:
331,302,239 ÷ 4 = 82,825,559.75
If the quotient is a whole number, then 4 and 82,825,559.75 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 | 331,302,239 | |
| -1 | 331,302,239 |
If you did it right, you will end up with this table:
| 1 | 17 | 31 | 97 | 527 | 1,649 | 3,007 | 6,481 | 51,119 | 110,177 | 200,911 | 628,657 | 3,415,487 | 10,687,169 | 19,488,367 | 331,302,239 |
| -1 | -17 | -31 | -97 | -527 | -1,649 | -3,007 | -6,481 | -51,119 | -110,177 | -200,911 | -628,657 | -3,415,487 | -10,687,169 | -19,488,367 | -331,302,239 |
