# Python Program to Check the Number is a Krishnamurthy Number

Write a Python program to check the number is a Krishnamurthy number or not using a while loop. Any number is a Krishnamurthy number if the sum of the factorial of its digits equals itself. In this Python example, we used the while loop to divide the number into digits. Next, the math factorial function finds the factorial of each digit. The if condition checks whether the sum of the factorial of individual digits equals a number. If true, it is a Krishnamurthy number.

```import math

Number = int(input("Enter the Number to Check Krishnamurthy Number = "))
Temp = Number
Sum = 0

while Temp > 0:
fact = 1
i = 1
rem = Temp % 10
fact = math.factorial(rem)
Sum = Sum + fact
Temp = Temp // 10

if Sum == Number:
print("\n%d is a Krishnamurthy Number." %Number)
else:
print("%d is Not a Krishnamurthy Number." %Number)```

In this Python example, we removed the math factorial function and used the nested while loops to check the number is a Krishnamurthy number or not.

```Number = int(input("Enter the Number to Check Krishnamurthy Number = "))
Sum = 0
Temp = Number

while Temp > 0:
fact = 1
i = 1
rem = Temp % 10

while i <= rem:
fact = fact * i
i = i + 1
print('Factorial of %d = %d' %(rem, fact))
Sum = Sum + fact
Temp = Temp // 10

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

if Sum == Number:
print("\n%d is a Krishnamurthy Number." %Number)
else:
print("%d is Not a Krishnamurthy Number." %Number)```
``````Enter the Number to Check Krishnamurthy Number = 40585
Factorial of 5 = 120
Factorial of 8 = 40320
Factorial of 5 = 120
Factorial of 0 = 1
Factorial of 4 = 24
The Sum of the Digits Factorials = 40585

40585 is a Krishnamurthy Number.``````
