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 82,568,243, 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 | 82,568,243 | |
| -1 | -82,568,243 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 82,568,243.
Example:
1 x 82,568,243 = 82,568,243
and
-1 x -82,568,243 = 82,568,243
Notice both answers equal 82,568,243
With that explanation out of the way, let's continue. Next, we take the number 82,568,243 and divide it by 2:
82,568,243 ÷ 2 = 41,284,121.5
If the quotient is a whole number, then 2 and 41,284,121.5 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 | 82,568,243 | |
| -1 | -82,568,243 |
Now, we try dividing 82,568,243 by 3:
82,568,243 ÷ 3 = 27,522,747.6667
If the quotient is a whole number, then 3 and 27,522,747.6667 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 | 82,568,243 | |
| -1 | -82,568,243 |
Let's try dividing by 4:
82,568,243 ÷ 4 = 20,642,060.75
If the quotient is a whole number, then 4 and 20,642,060.75 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 | 82,568,243 | |
| -1 | 82,568,243 |
If you did it right, you will end up with this table:
| 1 | 19 | 71 | 97 | 631 | 1,349 | 1,843 | 6,887 | 11,989 | 44,801 | 61,207 | 130,853 | 851,219 | 1,162,933 | 4,345,697 | 82,568,243 |
| -1 | -19 | -71 | -97 | -631 | -1,349 | -1,843 | -6,887 | -11,989 | -44,801 | -61,207 | -130,853 | -851,219 | -1,162,933 | -4,345,697 | -82,568,243 |
