Which of the answer choices is a prime number? Select all that apply.
11 18 28 41 43
From the given answer choices, the prime numbers are: 11, 41, and 43.
To determine which of the answer choices are prime numbers, you need to know the definition of a prime number and check each answer choice individually.
A prime number is a number greater than 1 that is divisible only by 1 and itself. In other words, a prime number has exactly two distinct positive divisors.
To check whether an answer choice is prime, you can try dividing it by all the numbers from 2 up to the square root of the number. If any of these divisions result in an integer quotient, then the number is not prime. Otherwise, it is prime.
Once you understand this concept, you can look at each answer choice and perform the division test. If any of the divisions result in an integer quotient, the number is not prime. However, if none of the divisions produces an integer quotient, then the number is prime.
