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 122,330,113, 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 | 122,330,113 | |
| -1 | -122,330,113 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 122,330,113.
Example:
1 x 122,330,113 = 122,330,113
and
-1 x -122,330,113 = 122,330,113
Notice both answers equal 122,330,113
With that explanation out of the way, let's continue. Next, we take the number 122,330,113 and divide it by 2:
122,330,113 ÷ 2 = 61,165,056.5
If the quotient is a whole number, then 2 and 61,165,056.5 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 | 122,330,113 | |
| -1 | -122,330,113 |
Now, we try dividing 122,330,113 by 3:
122,330,113 ÷ 3 = 40,776,704.3333
If the quotient is a whole number, then 3 and 40,776,704.3333 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 | 122,330,113 | |
| -1 | -122,330,113 |
Let's try dividing by 4:
122,330,113 ÷ 4 = 30,582,528.25
If the quotient is a whole number, then 4 and 30,582,528.25 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 | 122,330,113 | |
| -1 | 122,330,113 |
If you did it right, you will end up with this table:
| 1 | 17 | 19 | 103 | 323 | 1,751 | 1,957 | 3,677 | 33,269 | 62,509 | 69,863 | 378,731 | 1,187,671 | 6,438,427 | 7,195,889 | 122,330,113 |
| -1 | -17 | -19 | -103 | -323 | -1,751 | -1,957 | -3,677 | -33,269 | -62,509 | -69,863 | -378,731 | -1,187,671 | -6,438,427 | -7,195,889 | -122,330,113 |
