How do you check if a number is prime?

  • Myth: All prime numbers are odd.
  • Myth: Prime numbers are rare.

    • Prime numbers are whole numbers greater than 1 that are divisible only by 1 and themselves. For example, 5 is a prime number because it can only be divided by 1 and 5. To determine if a number is prime, we need to check if it has any divisors other than 1 and itself. This can be done using various methods, including trial division, modular arithmetic, and primality tests.
