Jan 27, 2022 · Given a number n, check whether it's prime number or not using recursion. The idea is based on school method to check for prime numbers.

The number to be checked if a prime is x. The variable i is the divisor.(ie) x/2, (x/2)-1,...0. public int primes(int x, int i) { if(i==0) return 1; if(x%i==0) return 0; else primes(x, i-1); }

Here, we will discuss the program for prime number using recursion in Java. We are given with a number and need to check if its prime or not.

This is a Java Program to Find if a Number is Prime or Not using Recursion. A number is said to be a prime number if it is divisible only by itself and unity. Enter an integer as an input. Now we …

Method 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 …
