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 112,101,121, 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 | 112,101,121 | |
| -1 | -112,101,121 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 112,101,121.
Example:
1 x 112,101,121 = 112,101,121
and
-1 x -112,101,121 = 112,101,121
Notice both answers equal 112,101,121
With that explanation out of the way, let's continue. Next, we take the number 112,101,121 and divide it by 2:
112,101,121 ÷ 2 = 56,050,560.5
If the quotient is a whole number, then 2 and 56,050,560.5 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 | 112,101,121 | |
| -1 | -112,101,121 |
Now, we try dividing 112,101,121 by 3:
112,101,121 ÷ 3 = 37,367,040.3333
If the quotient is a whole number, then 3 and 37,367,040.3333 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 | 112,101,121 | |
| -1 | -112,101,121 |
Let's try dividing by 4:
112,101,121 ÷ 4 = 28,025,280.25
If the quotient is a whole number, then 4 and 28,025,280.25 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 | 112,101,121 | |
| -1 | 112,101,121 |
If you did it right, you will end up with this table:
| 1 | 11 | 19 | 59 | 209 | 649 | 1,121 | 9,091 | 12,331 | 100,001 | 172,729 | 536,369 | 1,900,019 | 5,900,059 | 10,191,011 | 112,101,121 |
| -1 | -11 | -19 | -59 | -209 | -649 | -1,121 | -9,091 | -12,331 | -100,001 | -172,729 | -536,369 | -1,900,019 | -5,900,059 | -10,191,011 | -112,101,121 |
