Write a function to calculate the factorial of a given number and return the result.
The factorial of a number n is the product of all positive integers less than or equal to n.
Example:
Input: 5
Output: 120
Explanation: 5! = 5 * 4 * 3 * 2 * 1 = 120
Note:
- The input number will always be a non-negative integer.
