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 331,113,097, 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 | 331,113,097 | |
| -1 | -331,113,097 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 331,113,097.
Example:
1 x 331,113,097 = 331,113,097
and
-1 x -331,113,097 = 331,113,097
Notice both answers equal 331,113,097
With that explanation out of the way, let's continue. Next, we take the number 331,113,097 and divide it by 2:
331,113,097 ÷ 2 = 165,556,548.5
If the quotient is a whole number, then 2 and 165,556,548.5 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 | 331,113,097 | |
| -1 | -331,113,097 |
Now, we try dividing 331,113,097 by 3:
331,113,097 ÷ 3 = 110,371,032.3333
If the quotient is a whole number, then 3 and 110,371,032.3333 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 | 331,113,097 | |
| -1 | -331,113,097 |
Let's try dividing by 4:
331,113,097 ÷ 4 = 82,778,274.25
If the quotient is a whole number, then 4 and 82,778,274.25 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 | 331,113,097 | |
| -1 | 331,113,097 |
If you did it right, you will end up with this table:
| 1 | 7 | 17 | 29 | 119 | 203 | 493 | 3,451 | 95,947 | 671,629 | 1,631,099 | 2,782,463 | 11,417,693 | 19,477,241 | 47,301,871 | 331,113,097 |
| -1 | -7 | -17 | -29 | -119 | -203 | -493 | -3,451 | -95,947 | -671,629 | -1,631,099 | -2,782,463 | -11,417,693 | -19,477,241 | -47,301,871 | -331,113,097 |
