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 6,820,825, 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 | 6,820,825 | |
| -1 | -6,820,825 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 6,820,825.
Example:
1 x 6,820,825 = 6,820,825
and
-1 x -6,820,825 = 6,820,825
Notice both answers equal 6,820,825
With that explanation out of the way, let's continue. Next, we take the number 6,820,825 and divide it by 2:
6,820,825 ÷ 2 = 3,410,412.5
If the quotient is a whole number, then 2 and 3,410,412.5 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 | 6,820,825 | |
| -1 | -6,820,825 |
Now, we try dividing 6,820,825 by 3:
6,820,825 ÷ 3 = 2,273,608.3333
If the quotient is a whole number, then 3 and 2,273,608.3333 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 | 6,820,825 | |
| -1 | -6,820,825 |
Let's try dividing by 4:
6,820,825 ÷ 4 = 1,705,206.25
If the quotient is a whole number, then 4 and 1,705,206.25 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 | 6,820,825 | |
| -1 | 6,820,825 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 17 | 25 | 55 | 85 | 187 | 275 | 425 | 935 | 1,459 | 4,675 | 7,295 | 16,049 | 24,803 | 36,475 | 80,245 | 124,015 | 272,833 | 401,225 | 620,075 | 1,364,165 | 6,820,825 |
| -1 | -5 | -11 | -17 | -25 | -55 | -85 | -187 | -275 | -425 | -935 | -1,459 | -4,675 | -7,295 | -16,049 | -24,803 | -36,475 | -80,245 | -124,015 | -272,833 | -401,225 | -620,075 | -1,364,165 | -6,820,825 |
