To identify the number classified as prime, we need to determine if each number in the given list is prime or not. A prime number is a number greater than 1 that has no positive divisors other than 1 and itself.
Let's go through each number in the list:
1. Number 39: To check if 39 is prime, we can try dividing it by all numbers less than itself. If it is evenly divisible by any of these numbers, then it is not prime. Dividing 39 by 2 gives us a remainder of 1, dividing by 3 gives us a remainder of 0, and dividing by 4 gives us a remainder of 3. Since 39 is divisible by 3, it is not prime.
2. Number 29: Again, we can check if 29 is prime by dividing it by all numbers less than itself. Dividing 29 by 2 gives us a remainder of 1, dividing by 3 gives us a remainder of 2, dividing by 4 gives us a remainder of 1, and so on. None of the numbers divide 29 evenly, so it is prime.
3. Number 49: Dividing 49 by 2 gives us a remainder of 1, dividing by 3 gives us a remainder of 1, dividing by 4 gives us a remainder of 1, and so on. Since 49 is divisible by 7 (7 x 7 = 49), it is not prime.
4. Number 69: Dividing 69 by 2 gives us a remainder of 1, dividing by 3 gives us a remainder of 0, dividing by 4 gives us a remainder of 1, and so on. Since 69 is divisible by 3, it is not prime.
From the given list, the only number classified as prime is number 29 (Option 2).
