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 111,231,205, 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 | 111,231,205 | |
| -1 | -111,231,205 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 111,231,205.
Example:
1 x 111,231,205 = 111,231,205
and
-1 x -111,231,205 = 111,231,205
Notice both answers equal 111,231,205
With that explanation out of the way, let's continue. Next, we take the number 111,231,205 and divide it by 2:
111,231,205 ÷ 2 = 55,615,602.5
If the quotient is a whole number, then 2 and 55,615,602.5 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 | 111,231,205 | |
| -1 | -111,231,205 |
Now, we try dividing 111,231,205 by 3:
111,231,205 ÷ 3 = 37,077,068.3333
If the quotient is a whole number, then 3 and 37,077,068.3333 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 | 111,231,205 | |
| -1 | -111,231,205 |
Let's try dividing by 4:
111,231,205 ÷ 4 = 27,807,801.25
If the quotient is a whole number, then 4 and 27,807,801.25 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 | 111,231,205 | |
| -1 | 111,231,205 |
If you did it right, you will end up with this table:
| 1 | 5 | 83 | 415 | 433 | 619 | 2,165 | 3,095 | 35,939 | 51,377 | 179,695 | 256,885 | 268,027 | 1,340,135 | 22,246,241 | 111,231,205 |
| -1 | -5 | -83 | -415 | -433 | -619 | -2,165 | -3,095 | -35,939 | -51,377 | -179,695 | -256,885 | -268,027 | -1,340,135 | -22,246,241 | -111,231,205 |
