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 122,111,435, 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 | 122,111,435 | |
| -1 | -122,111,435 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 122,111,435.
Example:
1 x 122,111,435 = 122,111,435
and
-1 x -122,111,435 = 122,111,435
Notice both answers equal 122,111,435
With that explanation out of the way, let's continue. Next, we take the number 122,111,435 and divide it by 2:
122,111,435 ÷ 2 = 61,055,717.5
If the quotient is a whole number, then 2 and 61,055,717.5 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 | 122,111,435 | |
| -1 | -122,111,435 |
Now, we try dividing 122,111,435 by 3:
122,111,435 ÷ 3 = 40,703,811.6667
If the quotient is a whole number, then 3 and 40,703,811.6667 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 | 122,111,435 | |
| -1 | -122,111,435 |
Let's try dividing by 4:
122,111,435 ÷ 4 = 30,527,858.75
If the quotient is a whole number, then 4 and 30,527,858.75 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 | 122,111,435 | |
| -1 | 122,111,435 |
If you did it right, you will end up with this table:
| 1 | 5 | 151 | 197 | 755 | 821 | 985 | 4,105 | 29,747 | 123,971 | 148,735 | 161,737 | 619,855 | 808,685 | 24,422,287 | 122,111,435 |
| -1 | -5 | -151 | -197 | -755 | -821 | -985 | -4,105 | -29,747 | -123,971 | -148,735 | -161,737 | -619,855 | -808,685 | -24,422,287 | -122,111,435 |
