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 111,442,243, 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 | 111,442,243 | |
| -1 | -111,442,243 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 111,442,243.
Example:
1 x 111,442,243 = 111,442,243
and
-1 x -111,442,243 = 111,442,243
Notice both answers equal 111,442,243
With that explanation out of the way, let's continue. Next, we take the number 111,442,243 and divide it by 2:
111,442,243 ÷ 2 = 55,721,121.5
If the quotient is a whole number, then 2 and 55,721,121.5 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 | 111,442,243 | |
| -1 | -111,442,243 |
Now, we try dividing 111,442,243 by 3:
111,442,243 ÷ 3 = 37,147,414.3333
If the quotient is a whole number, then 3 and 37,147,414.3333 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 | 111,442,243 | |
| -1 | -111,442,243 |
Let's try dividing by 4:
111,442,243 ÷ 4 = 27,860,560.75
If the quotient is a whole number, then 4 and 27,860,560.75 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 | 111,442,243 | |
| -1 | 111,442,243 |
If you did it right, you will end up with this table:
| 1 | 11 | 181 | 223 | 251 | 1,991 | 2,453 | 2,761 | 40,363 | 45,431 | 55,973 | 443,993 | 499,741 | 615,703 | 10,131,113 | 111,442,243 |
| -1 | -11 | -181 | -223 | -251 | -1,991 | -2,453 | -2,761 | -40,363 | -45,431 | -55,973 | -443,993 | -499,741 | -615,703 | -10,131,113 | -111,442,243 |
