Question

What are prime numbers? List all primes between 1 and 30.

Answer 1

Prime numbers are positive integers greater than 1 that are divisible only by 1 and themselves. In other words, they have exactly two positive divisors.

Here are the prime numbers between 1 and 30:

2, 3, 5, 7, 11, 13, 17, 19, 23, 29

Note that 1 is not a prime number, as it only has one positive divisor (itself). The number 2 is the only even prime number, and all other primes are odd. The set of prime numbers goes on infinitely, and there is no known pattern for the distribution of primes.

Answer 2

2, 3, 5, 7, 11, 13, 17, 19, 23, 29
