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 133,336,015, 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 | 133,336,015 | |
| -1 | -133,336,015 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 133,336,015.
Example:
1 x 133,336,015 = 133,336,015
and
-1 x -133,336,015 = 133,336,015
Notice both answers equal 133,336,015
With that explanation out of the way, let's continue. Next, we take the number 133,336,015 and divide it by 2:
133,336,015 ÷ 2 = 66,668,007.5
If the quotient is a whole number, then 2 and 66,668,007.5 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 | 133,336,015 | |
| -1 | -133,336,015 |
Now, we try dividing 133,336,015 by 3:
133,336,015 ÷ 3 = 44,445,338.3333
If the quotient is a whole number, then 3 and 44,445,338.3333 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 | 133,336,015 | |
| -1 | -133,336,015 |
Let's try dividing by 4:
133,336,015 ÷ 4 = 33,334,003.75
If the quotient is a whole number, then 4 and 33,334,003.75 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 | 133,336,015 | |
| -1 | 133,336,015 |
If you did it right, you will end up with this table:
| 1 | 5 | 17 | 19 | 85 | 95 | 323 | 1,615 | 82,561 | 412,805 | 1,403,537 | 1,568,659 | 7,017,685 | 7,843,295 | 26,667,203 | 133,336,015 |
| -1 | -5 | -17 | -19 | -85 | -95 | -323 | -1,615 | -82,561 | -412,805 | -1,403,537 | -1,568,659 | -7,017,685 | -7,843,295 | -26,667,203 | -133,336,015 |
