Write a user-defined function def HCF() to input two numbers from the user. The program calculates greatest common divisor of the two numbers inside the function. Finally, it returns the value to main program to display the result.

Sample Input: First Number: 25

Second Number: 60

HCF = 5

Write a user-defined function def Fact() to input 1 to 5 from the user. The program calculates the factorial of each number inside the function. Finally, it returns the values to main program to display the result.

Hint:

def Fact(n):
    f = 1
    for a in range(1, n+1):
        f = f * a
    return f
# main program
for i in range(1, 6):
    print("Factorial of", i, "=", Fact(i))
