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 12,534,625, 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 | 12,534,625 | |
| -1 | -12,534,625 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 12,534,625.
Example:
1 x 12,534,625 = 12,534,625
and
-1 x -12,534,625 = 12,534,625
Notice both answers equal 12,534,625
With that explanation out of the way, let's continue. Next, we take the number 12,534,625 and divide it by 2:
12,534,625 ÷ 2 = 6,267,312.5
If the quotient is a whole number, then 2 and 6,267,312.5 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 | 12,534,625 | |
| -1 | -12,534,625 |
Now, we try dividing 12,534,625 by 3:
12,534,625 ÷ 3 = 4,178,208.3333
If the quotient is a whole number, then 3 and 4,178,208.3333 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 | 12,534,625 | |
| -1 | -12,534,625 |
Let's try dividing by 4:
12,534,625 ÷ 4 = 3,133,656.25
If the quotient is a whole number, then 4 and 3,133,656.25 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 | 12,534,625 | |
| -1 | 12,534,625 |
If you did it right, you will end up with this table:
| 1 | 5 | 25 | 125 | 149 | 673 | 745 | 3,365 | 3,725 | 16,825 | 18,625 | 84,125 | 100,277 | 501,385 | 2,506,925 | 12,534,625 |
| -1 | -5 | -25 | -125 | -149 | -673 | -745 | -3,365 | -3,725 | -16,825 | -18,625 | -84,125 | -100,277 | -501,385 | -2,506,925 | -12,534,625 |
