Q. Which of the following numbers are prime?Multi-select Choices:(A) 17(B) 3(C) 8(D) 10
Check Prime Number 17: Step 1: Check if 17 is a prime number. A prime number has only two distinct positive divisors: 1 and itself. Testing 17, it is not divisible by 2, 3, 5, or 7, the primes less than its square root.
Check Prime Number 3: Step 2: Check if 3 is a prime number. 3 is only divisible by 1 and 3.
Check Prime Number 8: Step 3: Check if 8 is a prime number. 8 is divisible by 1, 2, 4, and 8. Since it has more than two divisors, it is not prime.
Check Prime Number 10: Step 4: Check if 10 is a prime number. 10 is divisible by 1, 2, 5, and 10. It has more than two divisors, so it's not prime.
