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 12,324,325, 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 | 12,324,325 | |
| -1 | -12,324,325 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 12,324,325.
Example:
1 x 12,324,325 = 12,324,325
and
-1 x -12,324,325 = 12,324,325
Notice both answers equal 12,324,325
With that explanation out of the way, let's continue. Next, we take the number 12,324,325 and divide it by 2:
12,324,325 ÷ 2 = 6,162,162.5
If the quotient is a whole number, then 2 and 6,162,162.5 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 | 12,324,325 | |
| -1 | -12,324,325 |
Now, we try dividing 12,324,325 by 3:
12,324,325 ÷ 3 = 4,108,108.3333
If the quotient is a whole number, then 3 and 4,108,108.3333 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 | 12,324,325 | |
| -1 | -12,324,325 |
Let's try dividing by 4:
12,324,325 ÷ 4 = 3,081,081.25
If the quotient is a whole number, then 4 and 3,081,081.25 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 | 12,324,325 | |
| -1 | 12,324,325 |
If you did it right, you will end up with this table:
| 1 | 5 | 13 | 25 | 65 | 169 | 325 | 845 | 2,917 | 4,225 | 14,585 | 37,921 | 72,925 | 189,605 | 492,973 | 948,025 | 2,464,865 | 12,324,325 |
| -1 | -5 | -13 | -25 | -65 | -169 | -325 | -845 | -2,917 | -4,225 | -14,585 | -37,921 | -72,925 | -189,605 | -492,973 | -948,025 | -2,464,865 | -12,324,325 |
