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 8,456,855, 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 | 8,456,855 | |
| -1 | -8,456,855 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 8,456,855.
Example:
1 x 8,456,855 = 8,456,855
and
-1 x -8,456,855 = 8,456,855
Notice both answers equal 8,456,855
With that explanation out of the way, let's continue. Next, we take the number 8,456,855 and divide it by 2:
8,456,855 ÷ 2 = 4,228,427.5
If the quotient is a whole number, then 2 and 4,228,427.5 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 | 8,456,855 | |
| -1 | -8,456,855 |
Now, we try dividing 8,456,855 by 3:
8,456,855 ÷ 3 = 2,818,951.6667
If the quotient is a whole number, then 3 and 2,818,951.6667 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 | 8,456,855 | |
| -1 | -8,456,855 |
Let's try dividing by 4:
8,456,855 ÷ 4 = 2,114,213.75
If the quotient is a whole number, then 4 and 2,114,213.75 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 | 8,456,855 | |
| -1 | 8,456,855 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 55 | 179 | 859 | 895 | 1,969 | 4,295 | 9,449 | 9,845 | 47,245 | 153,761 | 768,805 | 1,691,371 | 8,456,855 |
| -1 | -5 | -11 | -55 | -179 | -859 | -895 | -1,969 | -4,295 | -9,449 | -9,845 | -47,245 | -153,761 | -768,805 | -1,691,371 | -8,456,855 |
