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 133,715,081, 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 | 133,715,081 | |
| -1 | -133,715,081 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 133,715,081.
Example:
1 x 133,715,081 = 133,715,081
and
-1 x -133,715,081 = 133,715,081
Notice both answers equal 133,715,081
With that explanation out of the way, let's continue. Next, we take the number 133,715,081 and divide it by 2:
133,715,081 ÷ 2 = 66,857,540.5
If the quotient is a whole number, then 2 and 66,857,540.5 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 | 133,715,081 | |
| -1 | -133,715,081 |
Now, we try dividing 133,715,081 by 3:
133,715,081 ÷ 3 = 44,571,693.6667
If the quotient is a whole number, then 3 and 44,571,693.6667 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 | 133,715,081 | |
| -1 | -133,715,081 |
Let's try dividing by 4:
133,715,081 ÷ 4 = 33,428,770.25
If the quotient is a whole number, then 4 and 33,428,770.25 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 | 133,715,081 | |
| -1 | 133,715,081 |
If you did it right, you will end up with this table:
| 1 | 17 | 71 | 139 | 797 | 1,207 | 2,363 | 9,869 | 13,549 | 56,587 | 110,783 | 167,773 | 961,979 | 1,883,311 | 7,865,593 | 133,715,081 |
| -1 | -17 | -71 | -139 | -797 | -1,207 | -2,363 | -9,869 | -13,549 | -56,587 | -110,783 | -167,773 | -961,979 | -1,883,311 | -7,865,593 | -133,715,081 |
