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 8,352,185, 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 | 8,352,185 | |
| -1 | -8,352,185 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 8,352,185.
Example:
1 x 8,352,185 = 8,352,185
and
-1 x -8,352,185 = 8,352,185
Notice both answers equal 8,352,185
With that explanation out of the way, let's continue. Next, we take the number 8,352,185 and divide it by 2:
8,352,185 ÷ 2 = 4,176,092.5
If the quotient is a whole number, then 2 and 4,176,092.5 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 | 8,352,185 | |
| -1 | -8,352,185 |
Now, we try dividing 8,352,185 by 3:
8,352,185 ÷ 3 = 2,784,061.6667
If the quotient is a whole number, then 3 and 2,784,061.6667 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 | 8,352,185 | |
| -1 | -8,352,185 |
Let's try dividing by 4:
8,352,185 ÷ 4 = 2,088,046.25
If the quotient is a whole number, then 4 and 2,088,046.25 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 | 8,352,185 | |
| -1 | 8,352,185 |
If you did it right, you will end up with this table:
| 1 | 5 | 17 | 85 | 97 | 485 | 1,013 | 1,649 | 5,065 | 8,245 | 17,221 | 86,105 | 98,261 | 491,305 | 1,670,437 | 8,352,185 |
| -1 | -5 | -17 | -85 | -97 | -485 | -1,013 | -1,649 | -5,065 | -8,245 | -17,221 | -86,105 | -98,261 | -491,305 | -1,670,437 | -8,352,185 |
