Of the following numbers, which one is prime: $$ 32,42,29,15 $$ ? A) 29 B) 15 C) 32 D) 42

Question

UpStudy AI · Accepted Answer

The prime number is 29. Therefore, the correct answer is A) 29. To determine which of the given numbers is prime, we need to check each number for primality. A prime number is a natural number greater than 1 that has no positive divisors other than 1 and itself. 1. **32**: The divisors of 32 are 1, 2, 4, 8, 16, and 32. Since it has divisors other than 1 and itself, 32 is not prime. 2. **42**: The divisors of 42 are 1, 2, 3, 6, 7, 14, 21, and 42. Since it has divisors other than 1 and itself, 42 is not prime. 3. **29**: The only divisors of 29 are 1 and 29. Since it has no divisors other than 1 and itself, 29 is prime. 4. **15**: The divisors of 15 are 1, 3, 5, and 15. Since it has divisors other than 1 and itself, 15 is not prime. From the analysis, the only prime number among the options is: $$ \boxed{29} $$
