Python Program to Find Strong Number

Python Program to Find Strong Number

Python program to find strong number; In this tutorial, you will learn how to find whether a number is strong or not in python using for loop, while loop, and function.

Python Program to Find Strong Number

  • Python Program to find Strong Number using While Loop.
  • Strong Number in Python using For Loop.
  • Strong Number in Python using Function.

Python Program to find Strong Number using While Loop

  • Take input from the user.
  • Using two while loops, calculate the factorial of each of the digits in the number.
  • Next, sum of all the factorials of the digits.
  • Use if statement To check the sum of the factorials of the digits is equal to the by user-entered number.
  • Print the final result.
# Python Program to find Strong Number using while loop
 
Num = int(input(" Please Enter any Number: "))
Sum = 0
Temp = Num

while(Temp > 0):
    Factorial = 1
    i = 1
    Reminder = Temp % 10

    while(i <= Reminder):
        Factorial = Factorial * i
        i = i + 1

    print("\n Factorial of %d = %d" %(Reminder, Factorial))
    Sum = Sum + Factorial
    Temp = Temp // 10

print("\n Sum of Factorials of a Given Number %d = %d" %(Num, Sum))
    
if (Sum == Num):
    print(" %d is a Strong Number" %Num)
else:
    print(" %d is not a Strong Number" %Num)

Output

 Please Enter any Number:  165

 Factorial of 5 = 120

 Factorial of 6 = 720

 Factorial of 1 = 1

 Sum of Factorials of a Given Number 165 = 841
 165 is not a Strong Number

Strong Number in Python using For Loop

  • Take input from the user.
  • Using two For loops, calculate the factorial of each of the digits in the number.
  • Next, the sum of all the factorials of the digits.
  • Use if statement To check the sum of the factorials of the digits is equal to the by user-entered number.
  • Print the final result.
# Python Program to find Strong Number using for loop
 
Num = int(input(" Please Enter any Number: "))
Sum = 0
Temp = Num

while(Temp > 0):
    Factorial = 1
    Reminder = Temp % 10

    for i in range(1, Reminder + 1):
        Factorial = Factorial * i

    print("Factorial of %d = %d" %(Reminder, Factorial))
    Sum = Sum + Factorial
    Temp = Temp // 10

print("\n Sum of Factorials of a Given Number %d = %d" %(Num, Sum))
    
if (Sum == Num):
    print(" %d is a Strong Number" %Num)
else:
    print(" %d is not a Strong Number" %Num)

Output

Please Enter any Number:  145

Factorial of 5 = 120
Factorial of 4 = 24
Factorial of 1 = 1

Sum of Factorials of a Given Number 145 = 145
145 is a Strong Number

Strong Number in Python using Function.

  • Take input from the user.
  • Using a while loop with math factorial function, calculate the factorial of each of the digits in the number.
  • Next, the sum of all the factorials of the digits.
  • Use if statement To check the sum of the factorials of the digits is equal to the by user-entered number.
  • Print the final result.
# Python Program to find Strong Number using function

import math 

Num = int(input(" Please Enter any Number: "))
Sum = 0
Temp = Num

while(Temp > 0):
    Reminder = Temp % 10
    Factorial = math.factorial(Reminder)

    print("Factorial of %d = %d" %(Reminder, Factorial))
    Sum = Sum + Factorial
    Temp = Temp // 10

print("\n Sum of Factorials of a Given Number %d = %d" %(Num, Sum))
    
if (Sum == Num):
    print(" %d is a Strong Number" %Num)
else:
    print(" %d is not a Strong Number" %Num)

Output

Please Enter any Number:  40585
Factorial of 5 = 120
Factorial of 8 = 40320
Factorial of 5 = 120
Factorial of 0 = 1
Factorial of 4 = 24

Sum of Factorials of a Given Number 40585 = 40585
40585 is a Strong Number
