To solve this problem, we'll follow these steps:
Now, let's work through each step:
Step 1: Check divisibility.
The number 11 is greater than 2, so we check divisibility by smaller primes up to . The prime numbers less than or equal to 3 are 2 and 3.
- **Divisibility by 2:** 11 is an odd number, hence not divisible by 2.
- **Divisibility by 3:** Sum of digits of 11 is , which is not divisible by 3.
Step 2: Conclusion based on divisibility.
Since 11 is not divisible by any other numbers except 1 and 11 itself, it does not have any divisors other than 1 and itself. Therefore, 11 is a prime number.
Hence, the solution to the problem is is Prime.
