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 331,203,113, 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 | 331,203,113 | |
| -1 | -331,203,113 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 331,203,113.
Example:
1 x 331,203,113 = 331,203,113
and
-1 x -331,203,113 = 331,203,113
Notice both answers equal 331,203,113
With that explanation out of the way, let's continue. Next, we take the number 331,203,113 and divide it by 2:
331,203,113 ÷ 2 = 165,601,556.5
If the quotient is a whole number, then 2 and 165,601,556.5 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 | 331,203,113 | |
| -1 | -331,203,113 |
Now, we try dividing 331,203,113 by 3:
331,203,113 ÷ 3 = 110,401,037.6667
If the quotient is a whole number, then 3 and 110,401,037.6667 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 | 331,203,113 | |
| -1 | -331,203,113 |
Let's try dividing by 4:
331,203,113 ÷ 4 = 82,800,778.25
If the quotient is a whole number, then 4 and 82,800,778.25 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 | 331,203,113 | |
| -1 | 331,203,113 |
If you did it right, you will end up with this table:
| 1 | 29 | 113 | 211 | 479 | 3,277 | 6,119 | 13,891 | 23,843 | 54,127 | 101,069 | 691,447 | 1,569,683 | 2,931,001 | 11,420,797 | 331,203,113 |
| -1 | -29 | -113 | -211 | -479 | -3,277 | -6,119 | -13,891 | -23,843 | -54,127 | -101,069 | -691,447 | -1,569,683 | -2,931,001 | -11,420,797 | -331,203,113 |
