#rsisb Roll no.239 Coding task no.13 Foundation Level A **Prime Number Checker** is a simple program or tool that determines whether a given number is a **prime number** or not. A **prime number** is a number greater than **1** that can only be divided evenly by **1 and itself**. ### ✨ Examples: * **2** → Prime Number ✅ * **3** → Prime Number ✅ * **5** → Prime Number ✅ * **7** → Prime Number ✅ * **4** → Not a Prime Number ❌ (divisible by 1, 2, and 4) * **9** → Not a Prime Number ❌ (divisible by 1, 3, and 9) ### 💻 How It Works: The program takes a number as input and checks whether it has any divisors other than **1 and itself**. If it does not, the number is prime. Prime Number Checker projects are excellent for beginners because they help improve understanding of **loops, conditions, and logical thinking** in programming. 🚀💡 #PrimeNumber #Coding #Programming #JavaScript #Python #LearnToCode #ComputerScience 💻🔢✨
