Answer: 2, 23 are prime numbers while others are not
Step-by-step explanation:
To determine if a number is a prime number, we need to check if it has exactly two factors: 1 and itself.
Let's go through each number:
1. 2 is a prime number because it has only two factors: 1 and 2.
2. 10 is not a prime number because it has more than two factors (1, 2, 5, 10).
3. 16 is not a prime number because it has more than two factors (1, 2, 4, 8, 16).
4. 21 is not a prime number because it has more than two factors (1, 3, 7, 21).
5. 23 is a prime number because it has only two factors: 1 and 23.
6. 27 is not a prime number because it has more than two factors (1, 3, 9, 27).
So, out of the numbers given, only 2 and 23 are prime numbers. The rest have more than two factors, making them composite numbers.
I hope this explanation helps you understand the concept of prime numbers better! mark me as the brainliest pls
No, 10, 16, 21, and 27 all have factor pairs that don’t contain the number itself, so only 2 and 23 are prime
