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 122,222,125, 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 | 122,222,125 | |
| -1 | -122,222,125 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 122,222,125.
Example:
1 x 122,222,125 = 122,222,125
and
-1 x -122,222,125 = 122,222,125
Notice both answers equal 122,222,125
With that explanation out of the way, let's continue. Next, we take the number 122,222,125 and divide it by 2:
122,222,125 ÷ 2 = 61,111,062.5
If the quotient is a whole number, then 2 and 61,111,062.5 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 | 122,222,125 | |
| -1 | -122,222,125 |
Now, we try dividing 122,222,125 by 3:
122,222,125 ÷ 3 = 40,740,708.3333
If the quotient is a whole number, then 3 and 40,740,708.3333 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 | 122,222,125 | |
| -1 | -122,222,125 |
Let's try dividing by 4:
122,222,125 ÷ 4 = 30,555,531.25
If the quotient is a whole number, then 4 and 30,555,531.25 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 | 122,222,125 | |
| -1 | 122,222,125 |
If you did it right, you will end up with this table:
| 1 | 5 | 25 | 43 | 125 | 215 | 1,075 | 5,375 | 22,739 | 113,695 | 568,475 | 977,777 | 2,842,375 | 4,888,885 | 24,444,425 | 122,222,125 |
| -1 | -5 | -25 | -43 | -125 | -215 | -1,075 | -5,375 | -22,739 | -113,695 | -568,475 | -977,777 | -2,842,375 | -4,888,885 | -24,444,425 | -122,222,125 |
