Easy Ways to Identify Prime Numbers

  • Check divisibility – If a number is not divisible by any number other than 1 and itself, it is prime.

  • Skip even numbers after 2 – All even numbers greater than 2 are not prime.

  • Use the 6n ± 1 rule – Most primes (except 2 and 3) are one less or one more than a multiple of 6.
