1 to 50
The group of numbers that includes all prime numbers is 3 and 11. A prime number is defined as a natural number greater than 1 that has no positive divisors other than 1 and itself. The number 1 is not considered a prime number. Thus, the prime numbers in the given group are 3 and 11.
Of that group, 19 and 37 are prime.
