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 122,320,999, 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 | 122,320,999 | |
| -1 | -122,320,999 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 122,320,999.
Example:
1 x 122,320,999 = 122,320,999
and
-1 x -122,320,999 = 122,320,999
Notice both answers equal 122,320,999
With that explanation out of the way, let's continue. Next, we take the number 122,320,999 and divide it by 2:
122,320,999 ÷ 2 = 61,160,499.5
If the quotient is a whole number, then 2 and 61,160,499.5 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 | 122,320,999 | |
| -1 | -122,320,999 |
Now, we try dividing 122,320,999 by 3:
122,320,999 ÷ 3 = 40,773,666.3333
If the quotient is a whole number, then 3 and 40,773,666.3333 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 | 122,320,999 | |
| -1 | -122,320,999 |
Let's try dividing by 4:
122,320,999 ÷ 4 = 30,580,249.75
If the quotient is a whole number, then 4 and 30,580,249.75 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 | 122,320,999 | |
| -1 | 122,320,999 |
If you did it right, you will end up with this table:
| 1 | 41 | 101 | 109 | 271 | 4,141 | 4,469 | 11,009 | 11,111 | 27,371 | 29,539 | 451,369 | 1,122,211 | 1,211,099 | 2,983,439 | 122,320,999 |
| -1 | -41 | -101 | -109 | -271 | -4,141 | -4,469 | -11,009 | -11,111 | -27,371 | -29,539 | -451,369 | -1,122,211 | -1,211,099 | -2,983,439 | -122,320,999 |
