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 122,424,331, 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 | 122,424,331 | |
| -1 | -122,424,331 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 122,424,331.
Example:
1 x 122,424,331 = 122,424,331
and
-1 x -122,424,331 = 122,424,331
Notice both answers equal 122,424,331
With that explanation out of the way, let's continue. Next, we take the number 122,424,331 and divide it by 2:
122,424,331 ÷ 2 = 61,212,165.5
If the quotient is a whole number, then 2 and 61,212,165.5 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 | 122,424,331 | |
| -1 | -122,424,331 |
Now, we try dividing 122,424,331 by 3:
122,424,331 ÷ 3 = 40,808,110.3333
If the quotient is a whole number, then 3 and 40,808,110.3333 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 | 122,424,331 | |
| -1 | -122,424,331 |
Let's try dividing by 4:
122,424,331 ÷ 4 = 30,606,082.75
If the quotient is a whole number, then 4 and 30,606,082.75 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 | 122,424,331 | |
| -1 | 122,424,331 |
If you did it right, you will end up with this table:
| 1 | 23 | 47 | 109 | 1,039 | 1,081 | 2,507 | 5,123 | 23,897 | 48,833 | 113,251 | 117,829 | 1,123,159 | 2,604,773 | 5,322,797 | 122,424,331 |
| -1 | -23 | -47 | -109 | -1,039 | -1,081 | -2,507 | -5,123 | -23,897 | -48,833 | -113,251 | -117,829 | -1,123,159 | -2,604,773 | -5,322,797 | -122,424,331 |
