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 12,352,439, 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 | 12,352,439 | |
| -1 | -12,352,439 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 12,352,439.
Example:
1 x 12,352,439 = 12,352,439
and
-1 x -12,352,439 = 12,352,439
Notice both answers equal 12,352,439
With that explanation out of the way, let's continue. Next, we take the number 12,352,439 and divide it by 2:
12,352,439 ÷ 2 = 6,176,219.5
If the quotient is a whole number, then 2 and 6,176,219.5 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 | 12,352,439 | |
| -1 | -12,352,439 |
Now, we try dividing 12,352,439 by 3:
12,352,439 ÷ 3 = 4,117,479.6667
If the quotient is a whole number, then 3 and 4,117,479.6667 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 | 12,352,439 | |
| -1 | -12,352,439 |
Let's try dividing by 4:
12,352,439 ÷ 4 = 3,088,109.75
If the quotient is a whole number, then 4 and 3,088,109.75 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 | 12,352,439 | |
| -1 | 12,352,439 |
If you did it right, you will end up with this table:
| 1 | 11 | 41 | 61 | 449 | 451 | 671 | 2,501 | 4,939 | 18,409 | 27,389 | 27,511 | 202,499 | 301,279 | 1,122,949 | 12,352,439 |
| -1 | -11 | -41 | -61 | -449 | -451 | -671 | -2,501 | -4,939 | -18,409 | -27,389 | -27,511 | -202,499 | -301,279 | -1,122,949 | -12,352,439 |
