Hey guys, in this blog we will see a Python Program to Find Factorial of Number Using Recursion.

## Code

# Python Program to Find Factorial of Number Using Recursion def factorial_recur(n): if n == 1: return n else: return n*factorial_recur(n-1) num = int(input('Enter a number -> ')) # check if the number is negative if num < 0: print("Sorry, factorial does not exist for negative numbers") elif num == 0: print("The factorial of 0 is 1") else: print("The factorial of", num, "is", factorial_recur(num))

**Output**

Enter a number -> 5 The factorial of 5 is 120

Enter a number -> 10 The factorial of 10 is 3628800

Enter a number -> 7 The factorial of 7 is 5040

- Here we have used the
**concept of recursion**to calculate the factorial of a number entered by the user. - For example, the factorial of 5 can be calculated as follow:

**5! = 5X4!4! = 4X3!3! = 3X2!2! = 2X1!**
