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 8,230,205, 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 | 8,230,205 | |
| -1 | -8,230,205 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 8,230,205.
Example:
1 x 8,230,205 = 8,230,205
and
-1 x -8,230,205 = 8,230,205
Notice both answers equal 8,230,205
With that explanation out of the way, let's continue. Next, we take the number 8,230,205 and divide it by 2:
8,230,205 ÷ 2 = 4,115,102.5
If the quotient is a whole number, then 2 and 4,115,102.5 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 | 8,230,205 | |
| -1 | -8,230,205 |
Now, we try dividing 8,230,205 by 3:
8,230,205 ÷ 3 = 2,743,401.6667
If the quotient is a whole number, then 3 and 2,743,401.6667 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 | 8,230,205 | |
| -1 | -8,230,205 |
Let's try dividing by 4:
8,230,205 ÷ 4 = 2,057,551.25
If the quotient is a whole number, then 4 and 2,057,551.25 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 | 8,230,205 | |
| -1 | 8,230,205 |
If you did it right, you will end up with this table:
| 1 | 5 | 23 | 59 | 115 | 295 | 1,213 | 1,357 | 6,065 | 6,785 | 27,899 | 71,567 | 139,495 | 357,835 | 1,646,041 | 8,230,205 |
| -1 | -5 | -23 | -59 | -115 | -295 | -1,213 | -1,357 | -6,065 | -6,785 | -27,899 | -71,567 | -139,495 | -357,835 | -1,646,041 | -8,230,205 |
