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 122,231,255, 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 | 122,231,255 | |
| -1 | -122,231,255 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 122,231,255.
Example:
1 x 122,231,255 = 122,231,255
and
-1 x -122,231,255 = 122,231,255
Notice both answers equal 122,231,255
With that explanation out of the way, let's continue. Next, we take the number 122,231,255 and divide it by 2:
122,231,255 ÷ 2 = 61,115,627.5
If the quotient is a whole number, then 2 and 61,115,627.5 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 | 122,231,255 | |
| -1 | -122,231,255 |
Now, we try dividing 122,231,255 by 3:
122,231,255 ÷ 3 = 40,743,751.6667
If the quotient is a whole number, then 3 and 40,743,751.6667 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 | 122,231,255 | |
| -1 | -122,231,255 |
Let's try dividing by 4:
122,231,255 ÷ 4 = 30,557,813.75
If the quotient is a whole number, then 4 and 30,557,813.75 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 | 122,231,255 | |
| -1 | 122,231,255 |
If you did it right, you will end up with this table:
| 1 | 5 | 47 | 163 | 235 | 815 | 3,191 | 7,661 | 15,955 | 38,305 | 149,977 | 520,133 | 749,885 | 2,600,665 | 24,446,251 | 122,231,255 |
| -1 | -5 | -47 | -163 | -235 | -815 | -3,191 | -7,661 | -15,955 | -38,305 | -149,977 | -520,133 | -749,885 | -2,600,665 | -24,446,251 | -122,231,255 |
