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 12,066,635, 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 | 12,066,635 | |
| -1 | -12,066,635 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 12,066,635.
Example:
1 x 12,066,635 = 12,066,635
and
-1 x -12,066,635 = 12,066,635
Notice both answers equal 12,066,635
With that explanation out of the way, let's continue. Next, we take the number 12,066,635 and divide it by 2:
12,066,635 ÷ 2 = 6,033,317.5
If the quotient is a whole number, then 2 and 6,033,317.5 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 | 12,066,635 | |
| -1 | -12,066,635 |
Now, we try dividing 12,066,635 by 3:
12,066,635 ÷ 3 = 4,022,211.6667
If the quotient is a whole number, then 3 and 4,022,211.6667 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 | 12,066,635 | |
| -1 | -12,066,635 |
Let's try dividing by 4:
12,066,635 ÷ 4 = 3,016,658.75
If the quotient is a whole number, then 4 and 3,016,658.75 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 | 12,066,635 | |
| -1 | 12,066,635 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 307 | 1,123 | 1,535 | 2,149 | 5,615 | 7,861 | 10,745 | 39,305 | 344,761 | 1,723,805 | 2,413,327 | 12,066,635 |
| -1 | -5 | -7 | -35 | -307 | -1,123 | -1,535 | -2,149 | -5,615 | -7,861 | -10,745 | -39,305 | -344,761 | -1,723,805 | -2,413,327 | -12,066,635 |
