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 12,624,125, 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 | 12,624,125 | |
| -1 | -12,624,125 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 12,624,125.
Example:
1 x 12,624,125 = 12,624,125
and
-1 x -12,624,125 = 12,624,125
Notice both answers equal 12,624,125
With that explanation out of the way, let's continue. Next, we take the number 12,624,125 and divide it by 2:
12,624,125 ÷ 2 = 6,312,062.5
If the quotient is a whole number, then 2 and 6,312,062.5 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 | 12,624,125 | |
| -1 | -12,624,125 |
Now, we try dividing 12,624,125 by 3:
12,624,125 ÷ 3 = 4,208,041.6667
If the quotient is a whole number, then 3 and 4,208,041.6667 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 | 12,624,125 | |
| -1 | -12,624,125 |
Let's try dividing by 4:
12,624,125 ÷ 4 = 3,156,031.25
If the quotient is a whole number, then 4 and 3,156,031.25 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 | 12,624,125 | |
| -1 | 12,624,125 |
If you did it right, you will end up with this table:
| 1 | 5 | 23 | 25 | 115 | 125 | 575 | 2,875 | 4,391 | 21,955 | 100,993 | 109,775 | 504,965 | 548,875 | 2,524,825 | 12,624,125 |
| -1 | -5 | -23 | -25 | -115 | -125 | -575 | -2,875 | -4,391 | -21,955 | -100,993 | -109,775 | -504,965 | -548,875 | -2,524,825 | -12,624,125 |
