Explanation:

Step1: Recall prime - number definition

A prime number is a positive integer greater than 1 that has exactly two distinct positive divisors: 1 and itself.

Step2: Analyze 2

2 is greater than 1, and its divisors are 1 and 2. So 2 is prime.

Step3: Analyze 6

6 = 1×6 = 2×3. It has 1, 2, 3, 6 as divisors, so it's not prime.

Step4: Analyze 7

7 is greater than 1, and its divisors are 1 and 7. So 7 is prime.

Step5: Analyze 19

19 is greater than 1, and its divisors are 1 and 19. So 19 is prime.

Step6: Analyze 22

22 = 1×22 = 2×11. It has 1, 2, 11, 22 as divisors, so it's not prime.

Step7: Analyze 27

27 = 1×27 = 3×9. It has 1, 3, 9, 27 as divisors, so it's not prime.

Answer:

2, 7, 19
