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 82,606,459, 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 | 82,606,459 | |
| -1 | -82,606,459 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 82,606,459.
Example:
1 x 82,606,459 = 82,606,459
and
-1 x -82,606,459 = 82,606,459
Notice both answers equal 82,606,459
With that explanation out of the way, let's continue. Next, we take the number 82,606,459 and divide it by 2:
82,606,459 ÷ 2 = 41,303,229.5
If the quotient is a whole number, then 2 and 41,303,229.5 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 | 82,606,459 | |
| -1 | -82,606,459 |
Now, we try dividing 82,606,459 by 3:
82,606,459 ÷ 3 = 27,535,486.3333
If the quotient is a whole number, then 3 and 27,535,486.3333 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 | 82,606,459 | |
| -1 | -82,606,459 |
Let's try dividing by 4:
82,606,459 ÷ 4 = 20,651,614.75
If the quotient is a whole number, then 4 and 20,651,614.75 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 | 82,606,459 | |
| -1 | 82,606,459 |
If you did it right, you will end up with this table:
| 1 | 13 | 37 | 263 | 481 | 653 | 3,419 | 8,489 | 9,731 | 24,161 | 126,503 | 171,739 | 314,093 | 2,232,607 | 6,354,343 | 82,606,459 |
| -1 | -13 | -37 | -263 | -481 | -653 | -3,419 | -8,489 | -9,731 | -24,161 | -126,503 | -171,739 | -314,093 | -2,232,607 | -6,354,343 | -82,606,459 |
