97

Step by Step Explanation:

  1. A prime number is a natural number greater than 1 that has no positive divisors other than 1 and itself. We also know that even numbers are not prime numbers.
  2. The largest 2 digit number is 99. We know 99 is divisible by 1, 3 and itself.
    Next, we check for next odd two digit number less than 99, which is 97.
    97 is divisible by 1 and itself only.
  3. Therefore, the largest two digit prime number is 97.

Solution

The correct option is A 1As we already know that a prime number is a number that has only two factors, that is, 1 and the number itself. So, the largest 2-digit prime number = 97 Smallest 2-digit prime number = 11 GCF (Greatest Common Factor) of two or more numbers is the greatest number among all the common factors of the given numbers. Factors of 97 = 1 and 97 Factors of 11 = 1 and 11 ∴ Common factor = 1 Thus, GCF of 11 and 97 = 1 Therefore, the GCF of all the prime numbers is 1 only.
