Question

which of the following numbers are prime? 2 6 5 12 submit

Explanation:

Step1: Recall prime number definition

A prime number is a number greater than 1 that has no positive divisors other than 1 and itself.

Step2: Analyze each number

• For 2: Divisors are 1 and 2. So, 2 is prime.
• For 6: Divisors are 1, 2, 3, 6. Since it has divisors other than 1 and itself, 6 is not prime.
• For 5: Divisors are 1 and 5. So, 5 is prime.
• For 12: Divisors are 1, 2, 3, 4, 6, 12. Since it has divisors other than 1 and itself, 12 is not prime.

Answer:

The prime numbers are 2 and 5. So the correct selections should be the boxes for 2 and 5 (uncheck 6 and 12).
