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 111,202,135, 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 | 111,202,135 | |
| -1 | -111,202,135 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 111,202,135.
Example:
1 x 111,202,135 = 111,202,135
and
-1 x -111,202,135 = 111,202,135
Notice both answers equal 111,202,135
With that explanation out of the way, let's continue. Next, we take the number 111,202,135 and divide it by 2:
111,202,135 ÷ 2 = 55,601,067.5
If the quotient is a whole number, then 2 and 55,601,067.5 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 | 111,202,135 | |
| -1 | -111,202,135 |
Now, we try dividing 111,202,135 by 3:
111,202,135 ÷ 3 = 37,067,378.3333
If the quotient is a whole number, then 3 and 37,067,378.3333 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 | 111,202,135 | |
| -1 | -111,202,135 |
Let's try dividing by 4:
111,202,135 ÷ 4 = 27,800,533.75
If the quotient is a whole number, then 4 and 27,800,533.75 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 | 111,202,135 | |
| -1 | 111,202,135 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 55 | 383 | 1,915 | 4,213 | 5,279 | 21,065 | 26,395 | 58,069 | 290,345 | 2,021,857 | 10,109,285 | 22,240,427 | 111,202,135 |
| -1 | -5 | -11 | -55 | -383 | -1,915 | -4,213 | -5,279 | -21,065 | -26,395 | -58,069 | -290,345 | -2,021,857 | -10,109,285 | -22,240,427 | -111,202,135 |
