Factorial of a number can be calculated using both iterative and recursive methods.
Iterative method involves using a loop to multiply numbers from 1 to n.
Recursive method involves calling the function with n-1 until n reaches 1.
Example: Factorial of 5 using iterative method: 5! = 5*4*3*2*1 = 120
Example: Factorial of 5 using recursive method: 5! = 5 * 4!
Example: Factorial of 4 using recursive method: 4! = 4 * 3!
