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 111,123,031, 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 | 111,123,031 | |
| -1 | -111,123,031 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 111,123,031.
Example:
1 x 111,123,031 = 111,123,031
and
-1 x -111,123,031 = 111,123,031
Notice both answers equal 111,123,031
With that explanation out of the way, let's continue. Next, we take the number 111,123,031 and divide it by 2:
111,123,031 ÷ 2 = 55,561,515.5
If the quotient is a whole number, then 2 and 55,561,515.5 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 | 111,123,031 | |
| -1 | -111,123,031 |
Now, we try dividing 111,123,031 by 3:
111,123,031 ÷ 3 = 37,041,010.3333
If the quotient is a whole number, then 3 and 37,041,010.3333 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 | 111,123,031 | |
| -1 | -111,123,031 |
Let's try dividing by 4:
111,123,031 ÷ 4 = 27,780,757.75
If the quotient is a whole number, then 4 and 27,780,757.75 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 | 111,123,031 | |
| -1 | 111,123,031 |
If you did it right, you will end up with this table:
| 1 | 107 | 193 | 5,381 | 20,651 | 575,767 | 1,038,533 | 111,123,031 |
| -1 | -107 | -193 | -5,381 | -20,651 | -575,767 | -1,038,533 | -111,123,031 |
