Find the factorial of a given number

Write a program to use the loop to find the factorial of a given number.

The factorial (symbol: !) means to multiply all whole numbers from the chosen number down to 1.

For example: calculate the factorial of 5

5! = 5 × 4 × 3 × 2 × 1 = 120

Expected output:

120

Hint:

  • Set variable factorial =1 to store factorial of a given number
  • Iterate numbers starting from 1 to the given number n using for loop and range() function. (here, the loop will run five times because n is 5)
  • In each iteration, multiply factorial by the current number and assign it again to a factorial variable (factorial = factorial *i)
  • After the loop completes, print factorial

Solution:

num = 5
factorial = 1
if num < 0:
    print("Factorial does not exist for negative numbers")
elif num == 0:
    print("The factorial of 0 is 1")
else:
    # run loop 5 times
    for i in range(1, num + 1):
        # multiply factorial by current number
        factorial = factorial * i
    print("The factorial of", num, "is", factorial)
