write a solution to determine if a number is a prime number

Comment

def is_prime?(number)
  # Prime numbers are greater than 1
  return false if number <= 1

  # Check for divisors from 2 to the square root of the number (to optimize the algorithm)
  # If any divisor is found, the number is not prime
  (2..Math.sqrt(number)).each do |divisor|
    return false if number % divisor == 0
  end

  # If no divisors are found, the number is prime
  return true
end

# Test cases
puts is_prime?(2)     # Output: true
puts is_prime?(17)    # Output: true
puts is_prime?(29)    # Output: true
puts is_prime?(30)    # Output: false
puts is_prime?(100)   # Output: false
