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 111,012,031, 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 | 111,012,031 | |
| -1 | -111,012,031 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 111,012,031.
Example:
1 x 111,012,031 = 111,012,031
and
-1 x -111,012,031 = 111,012,031
Notice both answers equal 111,012,031
With that explanation out of the way, let's continue. Next, we take the number 111,012,031 and divide it by 2:
111,012,031 ÷ 2 = 55,506,015.5
If the quotient is a whole number, then 2 and 55,506,015.5 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 | 111,012,031 | |
| -1 | -111,012,031 |
Now, we try dividing 111,012,031 by 3:
111,012,031 ÷ 3 = 37,004,010.3333
If the quotient is a whole number, then 3 and 37,004,010.3333 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 | 111,012,031 | |
| -1 | -111,012,031 |
Let's try dividing by 4:
111,012,031 ÷ 4 = 27,753,007.75
If the quotient is a whole number, then 4 and 27,753,007.75 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 | 111,012,031 | |
| -1 | 111,012,031 |
If you did it right, you will end up with this table:
| 1 | 13 | 109 | 157 | 499 | 1,417 | 2,041 | 6,487 | 17,113 | 54,391 | 78,343 | 222,469 | 707,083 | 1,018,459 | 8,539,387 | 111,012,031 |
| -1 | -13 | -109 | -157 | -499 | -1,417 | -2,041 | -6,487 | -17,113 | -54,391 | -78,343 | -222,469 | -707,083 | -1,018,459 | -8,539,387 | -111,012,031 |
