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 12,665,825, 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 | 12,665,825 | |
| -1 | -12,665,825 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 12,665,825.
Example:
1 x 12,665,825 = 12,665,825
and
-1 x -12,665,825 = 12,665,825
Notice both answers equal 12,665,825
With that explanation out of the way, let's continue. Next, we take the number 12,665,825 and divide it by 2:
12,665,825 ÷ 2 = 6,332,912.5
If the quotient is a whole number, then 2 and 6,332,912.5 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 | 12,665,825 | |
| -1 | -12,665,825 |
Now, we try dividing 12,665,825 by 3:
12,665,825 ÷ 3 = 4,221,941.6667
If the quotient is a whole number, then 3 and 4,221,941.6667 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 | 12,665,825 | |
| -1 | -12,665,825 |
Let's try dividing by 4:
12,665,825 ÷ 4 = 3,166,456.25
If the quotient is a whole number, then 4 and 3,166,456.25 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 | 12,665,825 | |
| -1 | 12,665,825 |
If you did it right, you will end up with this table:
| 1 | 5 | 25 | 31 | 59 | 155 | 277 | 295 | 775 | 1,385 | 1,475 | 1,829 | 6,925 | 8,587 | 9,145 | 16,343 | 42,935 | 45,725 | 81,715 | 214,675 | 408,575 | 506,633 | 2,533,165 | 12,665,825 |
| -1 | -5 | -25 | -31 | -59 | -155 | -277 | -295 | -775 | -1,385 | -1,475 | -1,829 | -6,925 | -8,587 | -9,145 | -16,343 | -42,935 | -45,725 | -81,715 | -214,675 | -408,575 | -506,633 | -2,533,165 | -12,665,825 |
