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 12,456,395, 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 | 12,456,395 | |
| -1 | -12,456,395 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 12,456,395.
Example:
1 x 12,456,395 = 12,456,395
and
-1 x -12,456,395 = 12,456,395
Notice both answers equal 12,456,395
With that explanation out of the way, let's continue. Next, we take the number 12,456,395 and divide it by 2:
12,456,395 ÷ 2 = 6,228,197.5
If the quotient is a whole number, then 2 and 6,228,197.5 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 | 12,456,395 | |
| -1 | -12,456,395 |
Now, we try dividing 12,456,395 by 3:
12,456,395 ÷ 3 = 4,152,131.6667
If the quotient is a whole number, then 3 and 4,152,131.6667 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 | 12,456,395 | |
| -1 | -12,456,395 |
Let's try dividing by 4:
12,456,395 ÷ 4 = 3,114,098.75
If the quotient is a whole number, then 4 and 3,114,098.75 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 | 12,456,395 | |
| -1 | 12,456,395 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 479 | 743 | 2,395 | 3,353 | 3,715 | 5,201 | 16,765 | 26,005 | 355,897 | 1,779,485 | 2,491,279 | 12,456,395 |
| -1 | -5 | -7 | -35 | -479 | -743 | -2,395 | -3,353 | -3,715 | -5,201 | -16,765 | -26,005 | -355,897 | -1,779,485 | -2,491,279 | -12,456,395 |
