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 131,631,731, 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 | 131,631,731 | |
| -1 | -131,631,731 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 131,631,731.
Example:
1 x 131,631,731 = 131,631,731
and
-1 x -131,631,731 = 131,631,731
Notice both answers equal 131,631,731
With that explanation out of the way, let's continue. Next, we take the number 131,631,731 and divide it by 2:
131,631,731 ÷ 2 = 65,815,865.5
If the quotient is a whole number, then 2 and 65,815,865.5 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 | 131,631,731 | |
| -1 | -131,631,731 |
Now, we try dividing 131,631,731 by 3:
131,631,731 ÷ 3 = 43,877,243.6667
If the quotient is a whole number, then 3 and 43,877,243.6667 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 | 131,631,731 | |
| -1 | -131,631,731 |
Let's try dividing by 4:
131,631,731 ÷ 4 = 32,907,932.75
If the quotient is a whole number, then 4 and 32,907,932.75 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 | 131,631,731 | |
| -1 | 131,631,731 |
If you did it right, you will end up with this table:
| 1 | 7 | 11 | 17 | 77 | 119 | 187 | 1,309 | 100,559 | 703,913 | 1,106,149 | 1,709,503 | 7,743,043 | 11,966,521 | 18,804,533 | 131,631,731 |
| -1 | -7 | -11 | -17 | -77 | -119 | -187 | -1,309 | -100,559 | -703,913 | -1,106,149 | -1,709,503 | -7,743,043 | -11,966,521 | -18,804,533 | -131,631,731 |
