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 6,627,805, 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 | 6,627,805 | |
| -1 | -6,627,805 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 6,627,805.
Example:
1 x 6,627,805 = 6,627,805
and
-1 x -6,627,805 = 6,627,805
Notice both answers equal 6,627,805
With that explanation out of the way, let's continue. Next, we take the number 6,627,805 and divide it by 2:
6,627,805 ÷ 2 = 3,313,902.5
If the quotient is a whole number, then 2 and 3,313,902.5 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 | 6,627,805 | |
| -1 | -6,627,805 |
Now, we try dividing 6,627,805 by 3:
6,627,805 ÷ 3 = 2,209,268.3333
If the quotient is a whole number, then 3 and 2,209,268.3333 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 | 6,627,805 | |
| -1 | -6,627,805 |
Let's try dividing by 4:
6,627,805 ÷ 4 = 1,656,951.25
If the quotient is a whole number, then 4 and 1,656,951.25 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 | 6,627,805 | |
| -1 | 6,627,805 |
If you did it right, you will end up with this table:
| 1 | 5 | 29 | 43 | 145 | 215 | 1,063 | 1,247 | 5,315 | 6,235 | 30,827 | 45,709 | 154,135 | 228,545 | 1,325,561 | 6,627,805 |
| -1 | -5 | -29 | -43 | -145 | -215 | -1,063 | -1,247 | -5,315 | -6,235 | -30,827 | -45,709 | -154,135 | -228,545 | -1,325,561 | -6,627,805 |
