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 122,023,121, 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 | 122,023,121 | |
| -1 | -122,023,121 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 122,023,121.
Example:
1 x 122,023,121 = 122,023,121
and
-1 x -122,023,121 = 122,023,121
Notice both answers equal 122,023,121
With that explanation out of the way, let's continue. Next, we take the number 122,023,121 and divide it by 2:
122,023,121 ÷ 2 = 61,011,560.5
If the quotient is a whole number, then 2 and 61,011,560.5 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 | 122,023,121 | |
| -1 | -122,023,121 |
Now, we try dividing 122,023,121 by 3:
122,023,121 ÷ 3 = 40,674,373.6667
If the quotient is a whole number, then 3 and 40,674,373.6667 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 | 122,023,121 | |
| -1 | -122,023,121 |
Let's try dividing by 4:
122,023,121 ÷ 4 = 30,505,780.25
If the quotient is a whole number, then 4 and 30,505,780.25 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 | 122,023,121 | |
| -1 | 122,023,121 |
If you did it right, you will end up with this table:
| 1 | 11 | 43 | 107 | 473 | 1,177 | 2,411 | 4,601 | 26,521 | 50,611 | 103,673 | 257,977 | 1,140,403 | 2,837,747 | 11,093,011 | 122,023,121 |
| -1 | -11 | -43 | -107 | -473 | -1,177 | -2,411 | -4,601 | -26,521 | -50,611 | -103,673 | -257,977 | -1,140,403 | -2,837,747 | -11,093,011 | -122,023,121 |
