in a krishnamurthy number the sum of factorial of each digit of the number is equal to the number . oh its kaprekar number in a kaprekar number you will have to square the number then if the sum of the digits of the square of the number is equal to the number then it is a kaprekar number eg =9 square of 9 = 81 ; 8+1=9 hence 9 is a kaprekar number
thank you
