2 days ago · A prime number is a natural number greater than 1 and is completely divisible only by 1 and itself. In this article, we will learn how to check whether the given number is a prime number or not in C. Examples: Input: n = 29 Output: 29 is Prime Explanation: 29 has no divisors other than 1 and 29 itself. Hence, it is a prime number. Input: n = 15
