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 8,204,581, 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 | 8,204,581 | |
| -1 | -8,204,581 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 8,204,581.
Example:
1 x 8,204,581 = 8,204,581
and
-1 x -8,204,581 = 8,204,581
Notice both answers equal 8,204,581
With that explanation out of the way, let's continue. Next, we take the number 8,204,581 and divide it by 2:
8,204,581 ÷ 2 = 4,102,290.5
If the quotient is a whole number, then 2 and 4,102,290.5 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 | 8,204,581 | |
| -1 | -8,204,581 |
Now, we try dividing 8,204,581 by 3:
8,204,581 ÷ 3 = 2,734,860.3333
If the quotient is a whole number, then 3 and 2,734,860.3333 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 | 8,204,581 | |
| -1 | -8,204,581 |
Let's try dividing by 4:
8,204,581 ÷ 4 = 2,051,145.25
If the quotient is a whole number, then 4 and 2,051,145.25 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 | 8,204,581 | |
| -1 | 8,204,581 |
If you did it right, you will end up with this table:
| 1 | 7 | 11 | 77 | 127 | 839 | 889 | 1,397 | 5,873 | 9,229 | 9,779 | 64,603 | 106,553 | 745,871 | 1,172,083 | 8,204,581 |
| -1 | -7 | -11 | -77 | -127 | -839 | -889 | -1,397 | -5,873 | -9,229 | -9,779 | -64,603 | -106,553 | -745,871 | -1,172,083 | -8,204,581 |
