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 122,423,411, 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 | 122,423,411 | |
| -1 | -122,423,411 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 122,423,411.
Example:
1 x 122,423,411 = 122,423,411
and
-1 x -122,423,411 = 122,423,411
Notice both answers equal 122,423,411
With that explanation out of the way, let's continue. Next, we take the number 122,423,411 and divide it by 2:
122,423,411 ÷ 2 = 61,211,705.5
If the quotient is a whole number, then 2 and 61,211,705.5 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 | 122,423,411 | |
| -1 | -122,423,411 |
Now, we try dividing 122,423,411 by 3:
122,423,411 ÷ 3 = 40,807,803.6667
If the quotient is a whole number, then 3 and 40,807,803.6667 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 | 122,423,411 | |
| -1 | -122,423,411 |
Let's try dividing by 4:
122,423,411 ÷ 4 = 30,605,852.75
If the quotient is a whole number, then 4 and 30,605,852.75 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 | 122,423,411 | |
| -1 | 122,423,411 |
If you did it right, you will end up with this table:
| 1 | 11 | 23 | 253 | 673 | 719 | 7,403 | 7,909 | 15,479 | 16,537 | 170,269 | 181,907 | 483,887 | 5,322,757 | 11,129,401 | 122,423,411 |
| -1 | -11 | -23 | -253 | -673 | -719 | -7,403 | -7,909 | -15,479 | -16,537 | -170,269 | -181,907 | -483,887 | -5,322,757 | -11,129,401 | -122,423,411 |
