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 111,808,255, 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 | 111,808,255 | |
| -1 | -111,808,255 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 111,808,255.
Example:
1 x 111,808,255 = 111,808,255
and
-1 x -111,808,255 = 111,808,255
Notice both answers equal 111,808,255
With that explanation out of the way, let's continue. Next, we take the number 111,808,255 and divide it by 2:
111,808,255 ÷ 2 = 55,904,127.5
If the quotient is a whole number, then 2 and 55,904,127.5 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 | 111,808,255 | |
| -1 | -111,808,255 |
Now, we try dividing 111,808,255 by 3:
111,808,255 ÷ 3 = 37,269,418.3333
If the quotient is a whole number, then 3 and 37,269,418.3333 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 | 111,808,255 | |
| -1 | -111,808,255 |
Let's try dividing by 4:
111,808,255 ÷ 4 = 27,952,063.75
If the quotient is a whole number, then 4 and 27,952,063.75 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 | 111,808,255 | |
| -1 | 111,808,255 |
If you did it right, you will end up with this table:
| 1 | 5 | 13 | 19 | 65 | 95 | 247 | 1,235 | 90,533 | 452,665 | 1,176,929 | 1,720,127 | 5,884,645 | 8,600,635 | 22,361,651 | 111,808,255 |
| -1 | -5 | -13 | -19 | -65 | -95 | -247 | -1,235 | -90,533 | -452,665 | -1,176,929 | -1,720,127 | -5,884,645 | -8,600,635 | -22,361,651 | -111,808,255 |
