Which term is defined as a number that has exactly two distinct positive divisors?

• A. Composite Number
• B. Real Number
• C. Prime Number
• D. Rational Number

Answer: (C)

A number that has exactly two distinct positive divisors is a prime number. A divisor is a positive integer that divides the number evenly. For a prime, the only divisors are 1 and the number itself, and the number must be greater than 1. Examples include 2, 3, and 5. Numbers with more than two divisors are composite, like 4, which has divisors 1, 2, and 4. Some terms like real numbers or rational numbers describe broader classifications of numbers and do not specify how many divisors a number has. Notably, 1 has only one positive divisor (itself), so it is not prime. Therefore the term described is prime.
