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 6,685,855, 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 | 6,685,855 | |
| -1 | -6,685,855 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 6,685,855.
Example:
1 x 6,685,855 = 6,685,855
and
-1 x -6,685,855 = 6,685,855
Notice both answers equal 6,685,855
With that explanation out of the way, let's continue. Next, we take the number 6,685,855 and divide it by 2:
6,685,855 ÷ 2 = 3,342,927.5
If the quotient is a whole number, then 2 and 3,342,927.5 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 | 6,685,855 | |
| -1 | -6,685,855 |
Now, we try dividing 6,685,855 by 3:
6,685,855 ÷ 3 = 2,228,618.3333
If the quotient is a whole number, then 3 and 2,228,618.3333 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 | 6,685,855 | |
| -1 | -6,685,855 |
Let's try dividing by 4:
6,685,855 ÷ 4 = 1,671,463.75
If the quotient is a whole number, then 4 and 1,671,463.75 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 | 6,685,855 | |
| -1 | 6,685,855 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 43 | 55 | 121 | 215 | 257 | 473 | 605 | 1,285 | 2,365 | 2,827 | 5,203 | 11,051 | 14,135 | 26,015 | 31,097 | 55,255 | 121,561 | 155,485 | 607,805 | 1,337,171 | 6,685,855 |
| -1 | -5 | -11 | -43 | -55 | -121 | -215 | -257 | -473 | -605 | -1,285 | -2,365 | -2,827 | -5,203 | -11,051 | -14,135 | -26,015 | -31,097 | -55,255 | -121,561 | -155,485 | -607,805 | -1,337,171 | -6,685,855 |
