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 133,660,117, 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 | 133,660,117 | |
| -1 | -133,660,117 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 133,660,117.
Example:
1 x 133,660,117 = 133,660,117
and
-1 x -133,660,117 = 133,660,117
Notice both answers equal 133,660,117
With that explanation out of the way, let's continue. Next, we take the number 133,660,117 and divide it by 2:
133,660,117 ÷ 2 = 66,830,058.5
If the quotient is a whole number, then 2 and 66,830,058.5 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 | 133,660,117 | |
| -1 | -133,660,117 |
Now, we try dividing 133,660,117 by 3:
133,660,117 ÷ 3 = 44,553,372.3333
If the quotient is a whole number, then 3 and 44,553,372.3333 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 | 133,660,117 | |
| -1 | -133,660,117 |
Let's try dividing by 4:
133,660,117 ÷ 4 = 33,415,029.25
If the quotient is a whole number, then 4 and 33,415,029.25 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 | 133,660,117 | |
| -1 | 133,660,117 |
If you did it right, you will end up with this table:
| 1 | 19 | 53 | 331 | 401 | 1,007 | 6,289 | 7,619 | 17,543 | 21,253 | 132,731 | 333,317 | 403,807 | 2,521,889 | 7,034,743 | 133,660,117 |
| -1 | -19 | -53 | -331 | -401 | -1,007 | -6,289 | -7,619 | -17,543 | -21,253 | -132,731 | -333,317 | -403,807 | -2,521,889 | -7,034,743 | -133,660,117 |
