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 8,206,289, 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 | 8,206,289 | |
| -1 | -8,206,289 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 8,206,289.
Example:
1 x 8,206,289 = 8,206,289
and
-1 x -8,206,289 = 8,206,289
Notice both answers equal 8,206,289
With that explanation out of the way, let's continue. Next, we take the number 8,206,289 and divide it by 2:
8,206,289 ÷ 2 = 4,103,144.5
If the quotient is a whole number, then 2 and 4,103,144.5 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 | 8,206,289 | |
| -1 | -8,206,289 |
Now, we try dividing 8,206,289 by 3:
8,206,289 ÷ 3 = 2,735,429.6667
If the quotient is a whole number, then 3 and 2,735,429.6667 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 | 8,206,289 | |
| -1 | -8,206,289 |
Let's try dividing by 4:
8,206,289 ÷ 4 = 2,051,572.25
If the quotient is a whole number, then 4 and 2,051,572.25 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 | 8,206,289 | |
| -1 | 8,206,289 |
If you did it right, you will end up with this table:
| 1 | 7 | 13 | 31 | 91 | 217 | 403 | 2,821 | 2,909 | 20,363 | 37,817 | 90,179 | 264,719 | 631,253 | 1,172,327 | 8,206,289 |
| -1 | -7 | -13 | -31 | -91 | -217 | -403 | -2,821 | -2,909 | -20,363 | -37,817 | -90,179 | -264,719 | -631,253 | -1,172,327 | -8,206,289 |
