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 111,244,715, 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 | 111,244,715 | |
| -1 | -111,244,715 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 111,244,715.
Example:
1 x 111,244,715 = 111,244,715
and
-1 x -111,244,715 = 111,244,715
Notice both answers equal 111,244,715
With that explanation out of the way, let's continue. Next, we take the number 111,244,715 and divide it by 2:
111,244,715 ÷ 2 = 55,622,357.5
If the quotient is a whole number, then 2 and 55,622,357.5 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 | 111,244,715 | |
| -1 | -111,244,715 |
Now, we try dividing 111,244,715 by 3:
111,244,715 ÷ 3 = 37,081,571.6667
If the quotient is a whole number, then 3 and 37,081,571.6667 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 | 111,244,715 | |
| -1 | -111,244,715 |
Let's try dividing by 4:
111,244,715 ÷ 4 = 27,811,178.75
If the quotient is a whole number, then 4 and 27,811,178.75 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 | 111,244,715 | |
| -1 | 111,244,715 |
If you did it right, you will end up with this table:
| 1 | 5 | 19 | 95 | 523 | 2,239 | 2,615 | 9,937 | 11,195 | 42,541 | 49,685 | 212,705 | 1,170,997 | 5,854,985 | 22,248,943 | 111,244,715 |
| -1 | -5 | -19 | -95 | -523 | -2,239 | -2,615 | -9,937 | -11,195 | -42,541 | -49,685 | -212,705 | -1,170,997 | -5,854,985 | -22,248,943 | -111,244,715 |
