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 133,320,131, 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 | 133,320,131 | |
| -1 | -133,320,131 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 133,320,131.
Example:
1 x 133,320,131 = 133,320,131
and
-1 x -133,320,131 = 133,320,131
Notice both answers equal 133,320,131
With that explanation out of the way, let's continue. Next, we take the number 133,320,131 and divide it by 2:
133,320,131 ÷ 2 = 66,660,065.5
If the quotient is a whole number, then 2 and 66,660,065.5 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 | 133,320,131 | |
| -1 | -133,320,131 |
Now, we try dividing 133,320,131 by 3:
133,320,131 ÷ 3 = 44,440,043.6667
If the quotient is a whole number, then 3 and 44,440,043.6667 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 | 133,320,131 | |
| -1 | -133,320,131 |
Let's try dividing by 4:
133,320,131 ÷ 4 = 33,330,032.75
If the quotient is a whole number, then 4 and 33,330,032.75 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 | 133,320,131 | |
| -1 | 133,320,131 |
If you did it right, you will end up with this table:
| 1 | 7 | 19 | 49 | 89 | 133 | 623 | 931 | 1,609 | 1,691 | 4,361 | 11,263 | 11,837 | 30,571 | 78,841 | 82,859 | 143,201 | 213,997 | 1,002,407 | 1,497,979 | 2,720,819 | 7,016,849 | 19,045,733 | 133,320,131 |
| -1 | -7 | -19 | -49 | -89 | -133 | -623 | -931 | -1,609 | -1,691 | -4,361 | -11,263 | -11,837 | -30,571 | -78,841 | -82,859 | -143,201 | -213,997 | -1,002,407 | -1,497,979 | -2,720,819 | -7,016,849 | -19,045,733 | -133,320,131 |
