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 82,108,589, 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 | 82,108,589 | |
| -1 | -82,108,589 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 82,108,589.
Example:
1 x 82,108,589 = 82,108,589
and
-1 x -82,108,589 = 82,108,589
Notice both answers equal 82,108,589
With that explanation out of the way, let's continue. Next, we take the number 82,108,589 and divide it by 2:
82,108,589 ÷ 2 = 41,054,294.5
If the quotient is a whole number, then 2 and 41,054,294.5 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 | 82,108,589 | |
| -1 | -82,108,589 |
Now, we try dividing 82,108,589 by 3:
82,108,589 ÷ 3 = 27,369,529.6667
If the quotient is a whole number, then 3 and 27,369,529.6667 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 | 82,108,589 | |
| -1 | -82,108,589 |
Let's try dividing by 4:
82,108,589 ÷ 4 = 20,527,147.25
If the quotient is a whole number, then 4 and 20,527,147.25 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 | 82,108,589 | |
| -1 | 82,108,589 |
If you did it right, you will end up with this table:
| 1 | 17 | 59 | 71 | 1,003 | 1,153 | 1,207 | 4,189 | 19,601 | 68,027 | 71,213 | 81,863 | 1,156,459 | 1,391,671 | 4,829,917 | 82,108,589 |
| -1 | -17 | -59 | -71 | -1,003 | -1,153 | -1,207 | -4,189 | -19,601 | -68,027 | -71,213 | -81,863 | -1,156,459 | -1,391,671 | -4,829,917 | -82,108,589 |
