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 8,218,327, 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 | 8,218,327 | |
| -1 | -8,218,327 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 8,218,327.
Example:
1 x 8,218,327 = 8,218,327
and
-1 x -8,218,327 = 8,218,327
Notice both answers equal 8,218,327
With that explanation out of the way, let's continue. Next, we take the number 8,218,327 and divide it by 2:
8,218,327 ÷ 2 = 4,109,163.5
If the quotient is a whole number, then 2 and 4,109,163.5 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 | 8,218,327 | |
| -1 | -8,218,327 |
Now, we try dividing 8,218,327 by 3:
8,218,327 ÷ 3 = 2,739,442.3333
If the quotient is a whole number, then 3 and 2,739,442.3333 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 | 8,218,327 | |
| -1 | -8,218,327 |
Let's try dividing by 4:
8,218,327 ÷ 4 = 2,054,581.75
If the quotient is a whole number, then 4 and 2,054,581.75 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 | 8,218,327 | |
| -1 | 8,218,327 |
If you did it right, you will end up with this table:
| 1 | 13 | 17 | 41 | 221 | 533 | 697 | 907 | 9,061 | 11,791 | 15,419 | 37,187 | 200,447 | 483,431 | 632,179 | 8,218,327 |
| -1 | -13 | -17 | -41 | -221 | -533 | -697 | -907 | -9,061 | -11,791 | -15,419 | -37,187 | -200,447 | -483,431 | -632,179 | -8,218,327 |
