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 111,043,135, 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 | 111,043,135 | |
| -1 | -111,043,135 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 111,043,135.
Example:
1 x 111,043,135 = 111,043,135
and
-1 x -111,043,135 = 111,043,135
Notice both answers equal 111,043,135
With that explanation out of the way, let's continue. Next, we take the number 111,043,135 and divide it by 2:
111,043,135 ÷ 2 = 55,521,567.5
If the quotient is a whole number, then 2 and 55,521,567.5 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 | 111,043,135 | |
| -1 | -111,043,135 |
Now, we try dividing 111,043,135 by 3:
111,043,135 ÷ 3 = 37,014,378.3333
If the quotient is a whole number, then 3 and 37,014,378.3333 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 | 111,043,135 | |
| -1 | -111,043,135 |
Let's try dividing by 4:
111,043,135 ÷ 4 = 27,760,783.75
If the quotient is a whole number, then 4 and 27,760,783.75 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 | 111,043,135 | |
| -1 | 111,043,135 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 151 | 755 | 1,057 | 5,285 | 21,011 | 105,055 | 147,077 | 735,385 | 3,172,661 | 15,863,305 | 22,208,627 | 111,043,135 |
| -1 | -5 | -7 | -35 | -151 | -755 | -1,057 | -5,285 | -21,011 | -105,055 | -147,077 | -735,385 | -3,172,661 | -15,863,305 | -22,208,627 | -111,043,135 |
