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 122,423,413, 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 | 122,423,413 | |
| -1 | -122,423,413 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 122,423,413.
Example:
1 x 122,423,413 = 122,423,413
and
-1 x -122,423,413 = 122,423,413
Notice both answers equal 122,423,413
With that explanation out of the way, let's continue. Next, we take the number 122,423,413 and divide it by 2:
122,423,413 ÷ 2 = 61,211,706.5
If the quotient is a whole number, then 2 and 61,211,706.5 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 | 122,423,413 | |
| -1 | -122,423,413 |
Now, we try dividing 122,423,413 by 3:
122,423,413 ÷ 3 = 40,807,804.3333
If the quotient is a whole number, then 3 and 40,807,804.3333 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 | 122,423,413 | |
| -1 | -122,423,413 |
Let's try dividing by 4:
122,423,413 ÷ 4 = 30,605,853.25
If the quotient is a whole number, then 4 and 30,605,853.25 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 | 122,423,413 | |
| -1 | 122,423,413 |
If you did it right, you will end up with this table:
| 1 | 7 | 29 | 49 | 101 | 203 | 707 | 853 | 1,421 | 2,929 | 4,949 | 5,971 | 20,503 | 24,737 | 41,797 | 86,153 | 143,521 | 173,159 | 603,071 | 1,212,113 | 2,498,437 | 4,221,497 | 17,489,059 | 122,423,413 |
| -1 | -7 | -29 | -49 | -101 | -203 | -707 | -853 | -1,421 | -2,929 | -4,949 | -5,971 | -20,503 | -24,737 | -41,797 | -86,153 | -143,521 | -173,159 | -603,071 | -1,212,113 | -2,498,437 | -4,221,497 | -17,489,059 | -122,423,413 |
