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 6,777,775, 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 | 6,777,775 | |
| -1 | -6,777,775 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 6,777,775.
Example:
1 x 6,777,775 = 6,777,775
and
-1 x -6,777,775 = 6,777,775
Notice both answers equal 6,777,775
With that explanation out of the way, let's continue. Next, we take the number 6,777,775 and divide it by 2:
6,777,775 ÷ 2 = 3,388,887.5
If the quotient is a whole number, then 2 and 3,388,887.5 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 | 6,777,775 | |
| -1 | -6,777,775 |
Now, we try dividing 6,777,775 by 3:
6,777,775 ÷ 3 = 2,259,258.3333
If the quotient is a whole number, then 3 and 2,259,258.3333 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 | 6,777,775 | |
| -1 | -6,777,775 |
Let's try dividing by 4:
6,777,775 ÷ 4 = 1,694,443.75
If the quotient is a whole number, then 4 and 1,694,443.75 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 | 6,777,775 | |
| -1 | 6,777,775 |
If you did it right, you will end up with this table:
| 1 | 5 | 19 | 25 | 95 | 361 | 475 | 751 | 1,805 | 3,755 | 9,025 | 14,269 | 18,775 | 71,345 | 271,111 | 356,725 | 1,355,555 | 6,777,775 |
| -1 | -5 | -19 | -25 | -95 | -361 | -475 | -751 | -1,805 | -3,755 | -9,025 | -14,269 | -18,775 | -71,345 | -271,111 | -356,725 | -1,355,555 | -6,777,775 |
