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 100,131,317, 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 | 100,131,317 | |
| -1 | -100,131,317 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 100,131,317.
Example:
1 x 100,131,317 = 100,131,317
and
-1 x -100,131,317 = 100,131,317
Notice both answers equal 100,131,317
With that explanation out of the way, let's continue. Next, we take the number 100,131,317 and divide it by 2:
100,131,317 ÷ 2 = 50,065,658.5
If the quotient is a whole number, then 2 and 50,065,658.5 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 | 100,131,317 | |
| -1 | -100,131,317 |
Now, we try dividing 100,131,317 by 3:
100,131,317 ÷ 3 = 33,377,105.6667
If the quotient is a whole number, then 3 and 33,377,105.6667 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 | 100,131,317 | |
| -1 | -100,131,317 |
Let's try dividing by 4:
100,131,317 ÷ 4 = 25,032,829.25
If the quotient is a whole number, then 4 and 25,032,829.25 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 | 100,131,317 | |
| -1 | 100,131,317 |
If you did it right, you will end up with this table:
| 1 | 11 | 13 | 61 | 143 | 169 | 671 | 793 | 883 | 1,859 | 8,723 | 9,713 | 10,309 | 11,479 | 53,863 | 113,399 | 126,269 | 149,227 | 592,493 | 700,219 | 1,641,497 | 7,702,409 | 9,102,847 | 100,131,317 |
| -1 | -11 | -13 | -61 | -143 | -169 | -671 | -793 | -883 | -1,859 | -8,723 | -9,713 | -10,309 | -11,479 | -53,863 | -113,399 | -126,269 | -149,227 | -592,493 | -700,219 | -1,641,497 | -7,702,409 | -9,102,847 | -100,131,317 |
