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 12,322,405, 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 | 12,322,405 | |
| -1 | -12,322,405 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 12,322,405.
Example:
1 x 12,322,405 = 12,322,405
and
-1 x -12,322,405 = 12,322,405
Notice both answers equal 12,322,405
With that explanation out of the way, let's continue. Next, we take the number 12,322,405 and divide it by 2:
12,322,405 ÷ 2 = 6,161,202.5
If the quotient is a whole number, then 2 and 6,161,202.5 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 | 12,322,405 | |
| -1 | -12,322,405 |
Now, we try dividing 12,322,405 by 3:
12,322,405 ÷ 3 = 4,107,468.3333
If the quotient is a whole number, then 3 and 4,107,468.3333 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 | 12,322,405 | |
| -1 | -12,322,405 |
Let's try dividing by 4:
12,322,405 ÷ 4 = 3,080,601.25
If the quotient is a whole number, then 4 and 3,080,601.25 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 | 12,322,405 | |
| -1 | 12,322,405 |
If you did it right, you will end up with this table:
| 1 | 5 | 71 | 103 | 337 | 355 | 515 | 1,685 | 7,313 | 23,927 | 34,711 | 36,565 | 119,635 | 173,555 | 2,464,481 | 12,322,405 |
| -1 | -5 | -71 | -103 | -337 | -355 | -515 | -1,685 | -7,313 | -23,927 | -34,711 | -36,565 | -119,635 | -173,555 | -2,464,481 | -12,322,405 |
