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 111,214,103, 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 | 111,214,103 | |
| -1 | -111,214,103 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 111,214,103.
Example:
1 x 111,214,103 = 111,214,103
and
-1 x -111,214,103 = 111,214,103
Notice both answers equal 111,214,103
With that explanation out of the way, let's continue. Next, we take the number 111,214,103 and divide it by 2:
111,214,103 ÷ 2 = 55,607,051.5
If the quotient is a whole number, then 2 and 55,607,051.5 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 | 111,214,103 | |
| -1 | -111,214,103 |
Now, we try dividing 111,214,103 by 3:
111,214,103 ÷ 3 = 37,071,367.6667
If the quotient is a whole number, then 3 and 37,071,367.6667 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 | 111,214,103 | |
| -1 | -111,214,103 |
Let's try dividing by 4:
111,214,103 ÷ 4 = 27,803,525.75
If the quotient is a whole number, then 4 and 27,803,525.75 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 | 111,214,103 | |
| -1 | 111,214,103 |
If you did it right, you will end up with this table:
| 1 | 7 | 11 | 13 | 77 | 91 | 143 | 1,001 | 111,103 | 777,721 | 1,222,133 | 1,444,339 | 8,554,931 | 10,110,373 | 15,887,729 | 111,214,103 |
| -1 | -7 | -11 | -13 | -77 | -91 | -143 | -1,001 | -111,103 | -777,721 | -1,222,133 | -1,444,339 | -8,554,931 | -10,110,373 | -15,887,729 | -111,214,103 |
