A prime number is a number greater than 1 that can only be divided by 1 and itself. In other words, it has exactly two distinct divisors : 1 and the number itself. For example: 2 is a prime number because it can only be divided by 1 and 2. 3 is a prime number because it can only be divided by 1 and 3. 4 is NOT a prime number because it can be divided by 1, 2, and 4 (it has more than two divisors). 🧠 Key Points About Prime Numbers : The smallest prime number is 2, and it is the only even prime number. All other prime numbers are odd . The number 1 is not considered prime because it only has one divisor: itself. Some examples of prime numbers are: 2, 3, 5, 7, 11, 13, 17, 19, 23, 29 ... and so on. Prime numbers play a crucial role in mathematics , especially in number theory and cryptography , where they are used for creating secure systems.
