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 324,504,113, 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 | 324,504,113 | |
| -1 | -324,504,113 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 324,504,113.
Example:
1 x 324,504,113 = 324,504,113
and
-1 x -324,504,113 = 324,504,113
Notice both answers equal 324,504,113
With that explanation out of the way, let's continue. Next, we take the number 324,504,113 and divide it by 2:
324,504,113 ÷ 2 = 162,252,056.5
If the quotient is a whole number, then 2 and 162,252,056.5 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 | 324,504,113 | |
| -1 | -324,504,113 |
Now, we try dividing 324,504,113 by 3:
324,504,113 ÷ 3 = 108,168,037.6667
If the quotient is a whole number, then 3 and 108,168,037.6667 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 | 324,504,113 | |
| -1 | -324,504,113 |
Let's try dividing by 4:
324,504,113 ÷ 4 = 81,126,028.25
If the quotient is a whole number, then 4 and 81,126,028.25 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 | 324,504,113 | |
| -1 | 324,504,113 |
If you did it right, you will end up with this table:
| 1 | 29 | 79 | 197 | 719 | 2,291 | 5,713 | 15,563 | 20,851 | 56,801 | 141,643 | 451,327 | 1,647,229 | 4,107,647 | 11,189,797 | 324,504,113 |
| -1 | -29 | -79 | -197 | -719 | -2,291 | -5,713 | -15,563 | -20,851 | -56,801 | -141,643 | -451,327 | -1,647,229 | -4,107,647 | -11,189,797 | -324,504,113 |
