Question

what of the following are prime 3 19 4 6
Answer
what are all the prime numbers 6 5 9 12
Answered by GPT-4o
To determine if a number is prime, we need to check if it has any divisors other than 1 and itself.

Let's evaluate each number:

- **3**: The only divisors of 3 are 1 and 3. Therefore, 3 is a prime number.
- **19**: The only divisors of 19 are 1 and 19. Therefore, 19 is a prime number.
- **4**: The divisors of 4 are 1, 2, and 4. Since it has a divisor other than 1 and itself (2), 4 is not a prime number.
- **6**: The divisors of 6 are 1, 2, 3, and 6. Since it has divisors other than 1 and itself (2 and 3), 6 is not a prime number.

So, the prime numbers from the given list are **3** and **19**.

To determine which of the given numbers are prime, we need to evaluate each one to see if it has any divisors other than 1 and itself.

- **6**: The divisors of 6 are 1, 2, 3, and 6. Since it has divisors other than 1 and itself (2 and 3), 6 is not a prime number.
- **5**: The only divisors of 5 are 1 and 5. Therefore, 5 is a prime number.
- **9**: The divisors of 9 are 1, 3, and 9. Since it has divisors other than 1 and itself (e.g., 3), 9 is not a prime number.
- **12**: The divisors of 12 are 1, 2, 3, 4, 6, and 12. Since it has divisors other than 1 and itself, 12 is not a prime number.

So, the only prime number from the given list is **5**.
