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 331,100,195, 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 | 331,100,195 | |
| -1 | -331,100,195 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 331,100,195.
Example:
1 x 331,100,195 = 331,100,195
and
-1 x -331,100,195 = 331,100,195
Notice both answers equal 331,100,195
With that explanation out of the way, let's continue. Next, we take the number 331,100,195 and divide it by 2:
331,100,195 ÷ 2 = 165,550,097.5
If the quotient is a whole number, then 2 and 165,550,097.5 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 | 331,100,195 | |
| -1 | -331,100,195 |
Now, we try dividing 331,100,195 by 3:
331,100,195 ÷ 3 = 110,366,731.6667
If the quotient is a whole number, then 3 and 110,366,731.6667 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 | 331,100,195 | |
| -1 | -331,100,195 |
Let's try dividing by 4:
331,100,195 ÷ 4 = 82,775,048.75
If the quotient is a whole number, then 4 and 82,775,048.75 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 | 331,100,195 | |
| -1 | 331,100,195 |
If you did it right, you will end up with this table:
| 1 | 5 | 47 | 103 | 235 | 515 | 4,841 | 13,679 | 24,205 | 68,395 | 642,913 | 1,408,937 | 3,214,565 | 7,044,685 | 66,220,039 | 331,100,195 |
| -1 | -5 | -47 | -103 | -235 | -515 | -4,841 | -13,679 | -24,205 | -68,395 | -642,913 | -1,408,937 | -3,214,565 | -7,044,685 | -66,220,039 | -331,100,195 |
