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 111,441,143, 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 | 111,441,143 | |
| -1 | -111,441,143 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 111,441,143.
Example:
1 x 111,441,143 = 111,441,143
and
-1 x -111,441,143 = 111,441,143
Notice both answers equal 111,441,143
With that explanation out of the way, let's continue. Next, we take the number 111,441,143 and divide it by 2:
111,441,143 ÷ 2 = 55,720,571.5
If the quotient is a whole number, then 2 and 55,720,571.5 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 | 111,441,143 | |
| -1 | -111,441,143 |
Now, we try dividing 111,441,143 by 3:
111,441,143 ÷ 3 = 37,147,047.6667
If the quotient is a whole number, then 3 and 37,147,047.6667 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 | 111,441,143 | |
| -1 | -111,441,143 |
Let's try dividing by 4:
111,441,143 ÷ 4 = 27,860,285.75
If the quotient is a whole number, then 4 and 27,860,285.75 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 | 111,441,143 | |
| -1 | 111,441,143 |
If you did it right, you will end up with this table:
| 1 | 11 | 73 | 137 | 803 | 1,013 | 1,507 | 10,001 | 11,143 | 73,949 | 110,011 | 138,781 | 813,439 | 1,526,591 | 10,131,013 | 111,441,143 |
| -1 | -11 | -73 | -137 | -803 | -1,013 | -1,507 | -10,001 | -11,143 | -73,949 | -110,011 | -138,781 | -813,439 | -1,526,591 | -10,131,013 | -111,441,143 |
