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 82,662,109, 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 | 82,662,109 | |
| -1 | -82,662,109 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 82,662,109.
Example:
1 x 82,662,109 = 82,662,109
and
-1 x -82,662,109 = 82,662,109
Notice both answers equal 82,662,109
With that explanation out of the way, let's continue. Next, we take the number 82,662,109 and divide it by 2:
82,662,109 ÷ 2 = 41,331,054.5
If the quotient is a whole number, then 2 and 41,331,054.5 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 | 82,662,109 | |
| -1 | -82,662,109 |
Now, we try dividing 82,662,109 by 3:
82,662,109 ÷ 3 = 27,554,036.3333
If the quotient is a whole number, then 3 and 27,554,036.3333 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 | 82,662,109 | |
| -1 | -82,662,109 |
Let's try dividing by 4:
82,662,109 ÷ 4 = 20,665,527.25
If the quotient is a whole number, then 4 and 20,665,527.25 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 | 82,662,109 | |
| -1 | 82,662,109 |
If you did it right, you will end up with this table:
| 1 | 17 | 41 | 233 | 509 | 697 | 3,961 | 8,653 | 9,553 | 20,869 | 118,597 | 162,401 | 354,773 | 2,016,149 | 4,862,477 | 82,662,109 |
| -1 | -17 | -41 | -233 | -509 | -697 | -3,961 | -8,653 | -9,553 | -20,869 | -118,597 | -162,401 | -354,773 | -2,016,149 | -4,862,477 | -82,662,109 |
