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 6,395,825, 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 | 6,395,825 | |
| -1 | -6,395,825 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 6,395,825.
Example:
1 x 6,395,825 = 6,395,825
and
-1 x -6,395,825 = 6,395,825
Notice both answers equal 6,395,825
With that explanation out of the way, let's continue. Next, we take the number 6,395,825 and divide it by 2:
6,395,825 ÷ 2 = 3,197,912.5
If the quotient is a whole number, then 2 and 3,197,912.5 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 | 6,395,825 | |
| -1 | -6,395,825 |
Now, we try dividing 6,395,825 by 3:
6,395,825 ÷ 3 = 2,131,941.6667
If the quotient is a whole number, then 3 and 2,131,941.6667 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 | 6,395,825 | |
| -1 | -6,395,825 |
Let's try dividing by 4:
6,395,825 ÷ 4 = 1,598,956.25
If the quotient is a whole number, then 4 and 1,598,956.25 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 | 6,395,825 | |
| -1 | 6,395,825 |
If you did it right, you will end up with this table:
| 1 | 5 | 17 | 25 | 85 | 101 | 149 | 425 | 505 | 745 | 1,717 | 2,525 | 2,533 | 3,725 | 8,585 | 12,665 | 15,049 | 42,925 | 63,325 | 75,245 | 255,833 | 376,225 | 1,279,165 | 6,395,825 |
| -1 | -5 | -17 | -25 | -85 | -101 | -149 | -425 | -505 | -745 | -1,717 | -2,525 | -2,533 | -3,725 | -8,585 | -12,665 | -15,049 | -42,925 | -63,325 | -75,245 | -255,833 | -376,225 | -1,279,165 | -6,395,825 |
