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 82,086,863, 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 | 82,086,863 | |
| -1 | -82,086,863 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 82,086,863.
Example:
1 x 82,086,863 = 82,086,863
and
-1 x -82,086,863 = 82,086,863
Notice both answers equal 82,086,863
With that explanation out of the way, let's continue. Next, we take the number 82,086,863 and divide it by 2:
82,086,863 ÷ 2 = 41,043,431.5
If the quotient is a whole number, then 2 and 41,043,431.5 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 | 82,086,863 | |
| -1 | -82,086,863 |
Now, we try dividing 82,086,863 by 3:
82,086,863 ÷ 3 = 27,362,287.6667
If the quotient is a whole number, then 3 and 27,362,287.6667 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 | 82,086,863 | |
| -1 | -82,086,863 |
Let's try dividing by 4:
82,086,863 ÷ 4 = 20,521,715.75
If the quotient is a whole number, then 4 and 20,521,715.75 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 | 82,086,863 | |
| -1 | 82,086,863 |
If you did it right, you will end up with this table:
| 1 | 17 | 47 | 71 | 799 | 1,207 | 1,447 | 3,337 | 24,599 | 56,729 | 68,009 | 102,737 | 1,156,153 | 1,746,529 | 4,828,639 | 82,086,863 |
| -1 | -17 | -47 | -71 | -799 | -1,207 | -1,447 | -3,337 | -24,599 | -56,729 | -68,009 | -102,737 | -1,156,153 | -1,746,529 | -4,828,639 | -82,086,863 |
