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 6,866,665, 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 | 6,866,665 | |
| -1 | -6,866,665 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 6,866,665.
Example:
1 x 6,866,665 = 6,866,665
and
-1 x -6,866,665 = 6,866,665
Notice both answers equal 6,866,665
With that explanation out of the way, let's continue. Next, we take the number 6,866,665 and divide it by 2:
6,866,665 ÷ 2 = 3,433,332.5
If the quotient is a whole number, then 2 and 3,433,332.5 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 | 6,866,665 | |
| -1 | -6,866,665 |
Now, we try dividing 6,866,665 by 3:
6,866,665 ÷ 3 = 2,288,888.3333
If the quotient is a whole number, then 3 and 2,288,888.3333 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 | 6,866,665 | |
| -1 | -6,866,665 |
Let's try dividing by 4:
6,866,665 ÷ 4 = 1,716,666.25
If the quotient is a whole number, then 4 and 1,716,666.25 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 | 6,866,665 | |
| -1 | 6,866,665 |
If you did it right, you will end up with this table:
| 1 | 5 | 13 | 65 | 149 | 709 | 745 | 1,937 | 3,545 | 9,217 | 9,685 | 46,085 | 105,641 | 528,205 | 1,373,333 | 6,866,665 |
| -1 | -5 | -13 | -65 | -149 | -709 | -745 | -1,937 | -3,545 | -9,217 | -9,685 | -46,085 | -105,641 | -528,205 | -1,373,333 | -6,866,665 |
