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 110,220,121, 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 | 110,220,121 | |
| -1 | -110,220,121 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 110,220,121.
Example:
1 x 110,220,121 = 110,220,121
and
-1 x -110,220,121 = 110,220,121
Notice both answers equal 110,220,121
With that explanation out of the way, let's continue. Next, we take the number 110,220,121 and divide it by 2:
110,220,121 ÷ 2 = 55,110,060.5
If the quotient is a whole number, then 2 and 55,110,060.5 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 | 110,220,121 | |
| -1 | -110,220,121 |
Now, we try dividing 110,220,121 by 3:
110,220,121 ÷ 3 = 36,740,040.3333
If the quotient is a whole number, then 3 and 36,740,040.3333 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 | 110,220,121 | |
| -1 | -110,220,121 |
Let's try dividing by 4:
110,220,121 ÷ 4 = 27,555,030.25
If the quotient is a whole number, then 4 and 27,555,030.25 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 | 110,220,121 | |
| -1 | 110,220,121 |
If you did it right, you will end up with this table:
| 1 | 11 | 19 | 197 | 209 | 2,167 | 2,677 | 3,743 | 29,447 | 41,173 | 50,863 | 527,369 | 559,493 | 5,801,059 | 10,020,011 | 110,220,121 |
| -1 | -11 | -19 | -197 | -209 | -2,167 | -2,677 | -3,743 | -29,447 | -41,173 | -50,863 | -527,369 | -559,493 | -5,801,059 | -10,020,011 | -110,220,121 |
