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 12,663,625, 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 | 12,663,625 | |
| -1 | -12,663,625 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 12,663,625.
Example:
1 x 12,663,625 = 12,663,625
and
-1 x -12,663,625 = 12,663,625
Notice both answers equal 12,663,625
With that explanation out of the way, let's continue. Next, we take the number 12,663,625 and divide it by 2:
12,663,625 ÷ 2 = 6,331,812.5
If the quotient is a whole number, then 2 and 6,331,812.5 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 | 12,663,625 | |
| -1 | -12,663,625 |
Now, we try dividing 12,663,625 by 3:
12,663,625 ÷ 3 = 4,221,208.3333
If the quotient is a whole number, then 3 and 4,221,208.3333 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 | 12,663,625 | |
| -1 | -12,663,625 |
Let's try dividing by 4:
12,663,625 ÷ 4 = 3,165,906.25
If the quotient is a whole number, then 4 and 3,165,906.25 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 | 12,663,625 | |
| -1 | 12,663,625 |
If you did it right, you will end up with this table:
| 1 | 5 | 13 | 25 | 65 | 125 | 325 | 1,625 | 7,793 | 38,965 | 101,309 | 194,825 | 506,545 | 974,125 | 2,532,725 | 12,663,625 |
| -1 | -5 | -13 | -25 | -65 | -125 | -325 | -1,625 | -7,793 | -38,965 | -101,309 | -194,825 | -506,545 | -974,125 | -2,532,725 | -12,663,625 |
