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 82,662,107, 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 | 82,662,107 | |
| -1 | -82,662,107 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 82,662,107.
Example:
1 x 82,662,107 = 82,662,107
and
-1 x -82,662,107 = 82,662,107
Notice both answers equal 82,662,107
With that explanation out of the way, let's continue. Next, we take the number 82,662,107 and divide it by 2:
82,662,107 ÷ 2 = 41,331,053.5
If the quotient is a whole number, then 2 and 41,331,053.5 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 | 82,662,107 | |
| -1 | -82,662,107 |
Now, we try dividing 82,662,107 by 3:
82,662,107 ÷ 3 = 27,554,035.6667
If the quotient is a whole number, then 3 and 27,554,035.6667 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 | 82,662,107 | |
| -1 | -82,662,107 |
Let's try dividing by 4:
82,662,107 ÷ 4 = 20,665,526.75
If the quotient is a whole number, then 4 and 20,665,526.75 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 | 82,662,107 | |
| -1 | 82,662,107 |
If you did it right, you will end up with this table:
| 1 | 11 | 37 | 83 | 407 | 913 | 2,447 | 3,071 | 26,917 | 33,781 | 90,539 | 203,101 | 995,929 | 2,234,111 | 7,514,737 | 82,662,107 |
| -1 | -11 | -37 | -83 | -407 | -913 | -2,447 | -3,071 | -26,917 | -33,781 | -90,539 | -203,101 | -995,929 | -2,234,111 | -7,514,737 | -82,662,107 |
