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 6,661,835, 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 | 6,661,835 | |
| -1 | -6,661,835 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 6,661,835.
Example:
1 x 6,661,835 = 6,661,835
and
-1 x -6,661,835 = 6,661,835
Notice both answers equal 6,661,835
With that explanation out of the way, let's continue. Next, we take the number 6,661,835 and divide it by 2:
6,661,835 ÷ 2 = 3,330,917.5
If the quotient is a whole number, then 2 and 3,330,917.5 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 | 6,661,835 | |
| -1 | -6,661,835 |
Now, we try dividing 6,661,835 by 3:
6,661,835 ÷ 3 = 2,220,611.6667
If the quotient is a whole number, then 3 and 2,220,611.6667 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 | 6,661,835 | |
| -1 | -6,661,835 |
Let's try dividing by 4:
6,661,835 ÷ 4 = 1,665,458.75
If the quotient is a whole number, then 4 and 1,665,458.75 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 | 6,661,835 | |
| -1 | 6,661,835 |
If you did it right, you will end up with this table:
| 1 | 5 | 23 | 53 | 115 | 265 | 1,093 | 1,219 | 5,465 | 6,095 | 25,139 | 57,929 | 125,695 | 289,645 | 1,332,367 | 6,661,835 |
| -1 | -5 | -23 | -53 | -115 | -265 | -1,093 | -1,219 | -5,465 | -6,095 | -25,139 | -57,929 | -125,695 | -289,645 | -1,332,367 | -6,661,835 |
