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 331,030,331, 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 | 331,030,331 | |
| -1 | -331,030,331 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 331,030,331.
Example:
1 x 331,030,331 = 331,030,331
and
-1 x -331,030,331 = 331,030,331
Notice both answers equal 331,030,331
With that explanation out of the way, let's continue. Next, we take the number 331,030,331 and divide it by 2:
331,030,331 ÷ 2 = 165,515,165.5
If the quotient is a whole number, then 2 and 165,515,165.5 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 | 331,030,331 | |
| -1 | -331,030,331 |
Now, we try dividing 331,030,331 by 3:
331,030,331 ÷ 3 = 110,343,443.6667
If the quotient is a whole number, then 3 and 110,343,443.6667 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 | 331,030,331 | |
| -1 | -331,030,331 |
Let's try dividing by 4:
331,030,331 ÷ 4 = 82,757,582.75
If the quotient is a whole number, then 4 and 82,757,582.75 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 | 331,030,331 | |
| -1 | 331,030,331 |
If you did it right, you will end up with this table:
| 1 | 19 | 29 | 199 | 551 | 3,019 | 3,781 | 5,771 | 57,361 | 87,551 | 109,649 | 600,781 | 1,663,469 | 11,414,839 | 17,422,649 | 331,030,331 |
| -1 | -19 | -29 | -199 | -551 | -3,019 | -3,781 | -5,771 | -57,361 | -87,551 | -109,649 | -600,781 | -1,663,469 | -11,414,839 | -17,422,649 | -331,030,331 |
