WebMagic Number vs Happy Number. The only difference between magic numbers and happy numbers is that in a magic number we sum up all the digits of the number recursively until we get a signal digit i.e. 1. While in happy number, we recursively calculate the sum of the square of digits until we get a single digit 1. If this process results in an … WebOct 12, 2024 · Input : num1 = 3 num2 = 21. Output : LCM of 3 and 21 is 21. Relationship Between HCF and LCM To find the LCM of the given two numbers using recursion.

WebMethod 3: Using Recursion. We can also check whether a number is prime or not using a recursive function. To the recursive function, we pass the next potential factor as i and check if it is actually the factor of the number (i.e. n%i == 0), if so then we return false otherwise, we increment i and recursively call the function until i=n/2. WebApr 16, 2024 · Happy Number using Recursion in Java. In this example, let’s solve this problem using recursion. I have already explained the algorithm the logic remains the same.
