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 31,331,195, 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 | 31,331,195 | |
| -1 | -31,331,195 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 31,331,195.
Example:
1 x 31,331,195 = 31,331,195
and
-1 x -31,331,195 = 31,331,195
Notice both answers equal 31,331,195
With that explanation out of the way, let's continue. Next, we take the number 31,331,195 and divide it by 2:
31,331,195 ÷ 2 = 15,665,597.5
If the quotient is a whole number, then 2 and 15,665,597.5 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 | 31,331,195 | |
| -1 | -31,331,195 |
Now, we try dividing 31,331,195 by 3:
31,331,195 ÷ 3 = 10,443,731.6667
If the quotient is a whole number, then 3 and 10,443,731.6667 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 | 31,331,195 | |
| -1 | -31,331,195 |
Let's try dividing by 4:
31,331,195 ÷ 4 = 7,832,798.75
If the quotient is a whole number, then 4 and 7,832,798.75 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 | 31,331,195 | |
| -1 | 31,331,195 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 701 | 1,277 | 3,505 | 4,907 | 6,385 | 8,939 | 24,535 | 44,695 | 895,177 | 4,475,885 | 6,266,239 | 31,331,195 |
| -1 | -5 | -7 | -35 | -701 | -1,277 | -3,505 | -4,907 | -6,385 | -8,939 | -24,535 | -44,695 | -895,177 | -4,475,885 | -6,266,239 | -31,331,195 |
