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 12,504,365, 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 | 12,504,365 | |
| -1 | -12,504,365 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 12,504,365.
Example:
1 x 12,504,365 = 12,504,365
and
-1 x -12,504,365 = 12,504,365
Notice both answers equal 12,504,365
With that explanation out of the way, let's continue. Next, we take the number 12,504,365 and divide it by 2:
12,504,365 ÷ 2 = 6,252,182.5
If the quotient is a whole number, then 2 and 6,252,182.5 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 | 12,504,365 | |
| -1 | -12,504,365 |
Now, we try dividing 12,504,365 by 3:
12,504,365 ÷ 3 = 4,168,121.6667
If the quotient is a whole number, then 3 and 4,168,121.6667 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 | 12,504,365 | |
| -1 | -12,504,365 |
Let's try dividing by 4:
12,504,365 ÷ 4 = 3,126,091.25
If the quotient is a whole number, then 4 and 3,126,091.25 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 | 12,504,365 | |
| -1 | 12,504,365 |
If you did it right, you will end up with this table:
| 1 | 5 | 29 | 83 | 145 | 415 | 1,039 | 2,407 | 5,195 | 12,035 | 30,131 | 86,237 | 150,655 | 431,185 | 2,500,873 | 12,504,365 |
| -1 | -5 | -29 | -83 | -145 | -415 | -1,039 | -2,407 | -5,195 | -12,035 | -30,131 | -86,237 | -150,655 | -431,185 | -2,500,873 | -12,504,365 |
