Python Program to Check a Number is a Harshad Number

Write a Python program to check a number is a Harshad number or not using a while loop. If a number is divisible by the sum of the digits of a given number, it is a Harshad number. For instance, 156 is divisible by 12 ( 1 + 5 + 6) so, it is a Harshad number.

Number = int(input("Enter the Number to Check Harshad Number = "))
Sum = 0
rem = 0

Temp = Number
while Temp > 0:
    rem = Temp % 10
    Sum = Sum + rem
    Temp = Temp // 10

print("The Sum of the Digits = %d" %Sum)

if Number % Sum == 0:
    print("\n%d is a Harshad Number." %Number)
else:
    print("%d is Not a Harshad Number." %Number)
Python Program to Check a Number is a Harshad Number

In this Python program, we used the while loop to divide the digit and calculate all digits’ sum. Next, the if condition checks whether the number is divisible by sum. If Tue, it is a Harshad number.

def digitsSum(Number):
    Sum = rem = 0
    while Number > 0:
        rem = Number % 10
        Sum = Sum + rem
        Number = Number // 10
    return Sum


Number = int(input("Enter the Number to Check Harshad Number = "))
Sum = digitsSum(Number)

print("The Sum of the Digits = %d" %Sum)

if Number % Sum == 0:
    print("%d is a Harshad Number." %Number)
else:
    print("%d is Not a Harshad Number." %Number)
Enter the Number to Check Harshad Number = 481
The Sum of the Digits = 13
481 is a Harshad Number.

Enter the Number to Check Harshad Number = 472
The Sum of the Digits = 13
472 is Not a Harshad Number.

Python program to check whether a given number is a Harshad number or not using functions.

Sum = 0
def digitsSum(Number):
    global Sum
    if Number > 0:
        rem = Number % 10
        Sum = Sum + rem
        digitsSum(Number // 10)
    return Sum


Number = int(input("Enter the Number to Check Harshad Number = "))
Sum = digitsSum(Number)

if Number % Sum == 0:
    print("%d is a Harshad Number." %Number)
else:
    print("%d is Not a Harshad Number." %Number)
Enter the Number to Check Harshad Number = 92
92 is Not a Harshad Number.

Enter the Number to Check Harshad Number = 448
448 is a Harshad Number.
