Answer
The prime numbers in the list are 13, 3, and 11.
Solution
A prime number is only divisible by 1 and itself. Let's check each number:
• 24 is divisible by 2, 3, 4, and more, so it is not prime.
• 13 is only divisible by 1 and 13, so it is prime.
• 21 is divisible by 3 and 7, so it is not prime.
• 28 is divisible by 2, 4, 7, and 14, so it is not prime.
• 3 is only divisible by 1 and 3, so it is prime.
• 11 is only divisible by 1 and 11, so it is prime.
Therefore, the prime numbers in the list are 13, 3, and 11.

Prime numbers are those greater than 1 that have no divisors other than 1 and themselves. In your list, 13, 3, and 11 are prime numbers. The number 21 can be divided by 3 and 7, while 24 and 28 can be divided by numerous integers, making them composite. As a fun fact, the smallest prime number is 2—that’s right, the only even prime number! Every other even number can be divided by 2, making them non-prime. So as you explore the world of primes, remember that they are the building blocks of the number system!
