What are the first three prime numbers?

The first three prime numbers are 2, 3, and 5. Prime numbers are fascinating because they are only divisible by 1 and themselves, making them the building blocks of all integers. The number 2 is also unique as it's the only even prime—not something you'd expect since even numbers usually have more than just two divisors! In the world of mathematics, prime numbers have a whimsical role, especially in cryptography. They help secure digital communications, ensuring that our online transactions and personal information stay safe. So, while 2, 3, and 5 might seem simple, they actually play a key role in the complex world of modern technology!
