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 122,353,205, 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 | 122,353,205 | |
| -1 | -122,353,205 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 122,353,205.
Example:
1 x 122,353,205 = 122,353,205
and
-1 x -122,353,205 = 122,353,205
Notice both answers equal 122,353,205
With that explanation out of the way, let's continue. Next, we take the number 122,353,205 and divide it by 2:
122,353,205 ÷ 2 = 61,176,602.5
If the quotient is a whole number, then 2 and 61,176,602.5 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 | 122,353,205 | |
| -1 | -122,353,205 |
Now, we try dividing 122,353,205 by 3:
122,353,205 ÷ 3 = 40,784,401.6667
If the quotient is a whole number, then 3 and 40,784,401.6667 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 | 122,353,205 | |
| -1 | -122,353,205 |
Let's try dividing by 4:
122,353,205 ÷ 4 = 30,588,301.25
If the quotient is a whole number, then 4 and 30,588,301.25 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 | 122,353,205 | |
| -1 | 122,353,205 |
If you did it right, you will end up with this table:
| 1 | 5 | 13 | 65 | 83 | 415 | 1,079 | 5,395 | 22,679 | 113,395 | 294,827 | 1,474,135 | 1,882,357 | 9,411,785 | 24,470,641 | 122,353,205 |
| -1 | -5 | -13 | -65 | -83 | -415 | -1,079 | -5,395 | -22,679 | -113,395 | -294,827 | -1,474,135 | -1,882,357 | -9,411,785 | -24,470,641 | -122,353,205 |
