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 120,332,335, 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 | 120,332,335 | |
| -1 | -120,332,335 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 120,332,335.
Example:
1 x 120,332,335 = 120,332,335
and
-1 x -120,332,335 = 120,332,335
Notice both answers equal 120,332,335
With that explanation out of the way, let's continue. Next, we take the number 120,332,335 and divide it by 2:
120,332,335 ÷ 2 = 60,166,167.5
If the quotient is a whole number, then 2 and 60,166,167.5 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 | 120,332,335 | |
| -1 | -120,332,335 |
Now, we try dividing 120,332,335 by 3:
120,332,335 ÷ 3 = 40,110,778.3333
If the quotient is a whole number, then 3 and 40,110,778.3333 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 | 120,332,335 | |
| -1 | -120,332,335 |
Let's try dividing by 4:
120,332,335 ÷ 4 = 30,083,083.75
If the quotient is a whole number, then 4 and 30,083,083.75 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 | 120,332,335 | |
| -1 | 120,332,335 |
If you did it right, you will end up with this table:
| 1 | 5 | 41 | 67 | 205 | 335 | 2,747 | 8,761 | 13,735 | 43,805 | 359,201 | 586,987 | 1,796,005 | 2,934,935 | 24,066,467 | 120,332,335 |
| -1 | -5 | -41 | -67 | -205 | -335 | -2,747 | -8,761 | -13,735 | -43,805 | -359,201 | -586,987 | -1,796,005 | -2,934,935 | -24,066,467 | -120,332,335 |
