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 6,770,885, 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 | 6,770,885 | |
| -1 | -6,770,885 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 6,770,885.
Example:
1 x 6,770,885 = 6,770,885
and
-1 x -6,770,885 = 6,770,885
Notice both answers equal 6,770,885
With that explanation out of the way, let's continue. Next, we take the number 6,770,885 and divide it by 2:
6,770,885 ÷ 2 = 3,385,442.5
If the quotient is a whole number, then 2 and 3,385,442.5 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 | 6,770,885 | |
| -1 | -6,770,885 |
Now, we try dividing 6,770,885 by 3:
6,770,885 ÷ 3 = 2,256,961.6667
If the quotient is a whole number, then 3 and 2,256,961.6667 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 | 6,770,885 | |
| -1 | -6,770,885 |
Let's try dividing by 4:
6,770,885 ÷ 4 = 1,692,721.25
If the quotient is a whole number, then 4 and 1,692,721.25 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 | 6,770,885 | |
| -1 | 6,770,885 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 55 | 307 | 401 | 1,535 | 2,005 | 3,377 | 4,411 | 16,885 | 22,055 | 123,107 | 615,535 | 1,354,177 | 6,770,885 |
| -1 | -5 | -11 | -55 | -307 | -401 | -1,535 | -2,005 | -3,377 | -4,411 | -16,885 | -22,055 | -123,107 | -615,535 | -1,354,177 | -6,770,885 |
