Question: 1 / 400

Which of the following best defines prime numbers?

Numbers that have multiple factors

Numbers divisible by 1 and themselves

Prime numbers are defined as numbers that have exactly two distinct positive factors: 1 and the number itself. This unique characteristic is what sets prime numbers apart from other integers. For instance, the number 7 can only be divided evenly by 1 and 7, making it a prime number.

Focusing on the definition provided in the options, the choice aligning with this concept highlights that prime numbers are specifically defined by their divisibility. Other choices misrepresent prime numbers by suggesting they possess multiple factors, apply to all even numbers (only 2 is both prime and even), or equate them with composite numbers, which are defined as numbers with more than two factors. Each of these alternatives fails to acknowledge the fundamental property that defines the prime numbers, thereby reinforcing why the correct answer is essential for understanding their mathematical classification.
