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 122,310,113, 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 | 122,310,113 | |
| -1 | -122,310,113 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 122,310,113.
Example:
1 x 122,310,113 = 122,310,113
and
-1 x -122,310,113 = 122,310,113
Notice both answers equal 122,310,113
With that explanation out of the way, let's continue. Next, we take the number 122,310,113 and divide it by 2:
122,310,113 ÷ 2 = 61,155,056.5
If the quotient is a whole number, then 2 and 61,155,056.5 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 | 122,310,113 | |
| -1 | -122,310,113 |
Now, we try dividing 122,310,113 by 3:
122,310,113 ÷ 3 = 40,770,037.6667
If the quotient is a whole number, then 3 and 40,770,037.6667 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 | 122,310,113 | |
| -1 | -122,310,113 |
Let's try dividing by 4:
122,310,113 ÷ 4 = 30,577,528.25
If the quotient is a whole number, then 4 and 30,577,528.25 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 | 122,310,113 | |
| -1 | 122,310,113 |
If you did it right, you will end up with this table:
| 1 | 23 | 73 | 97 | 751 | 1,679 | 2,231 | 7,081 | 17,273 | 54,823 | 72,847 | 162,863 | 1,260,929 | 1,675,481 | 5,317,831 | 122,310,113 |
| -1 | -23 | -73 | -97 | -751 | -1,679 | -2,231 | -7,081 | -17,273 | -54,823 | -72,847 | -162,863 | -1,260,929 | -1,675,481 | -5,317,831 | -122,310,113 |
