The correct term for a whole number greater than 1 that has no divisors other than 1 and itself is a prime number. This definition highlights that prime numbers have exactly two distinct positive divisors, making them foundational in number theory. For instance, the number 5 is prime because its only divisors are 1 and 5.

Even numbers, composite numbers, and integers refer to different categories. An even number is any integer divisible by 2. A composite number is a whole number greater than 1 that has more than two positive divisors, indicating that it can be formed by multiplying smaller whole numbers together. Integers encompass all whole numbers, both positive and negative, as well as zero, and are not limited to any specific traits related to prime or composite classifications. Thus, the term that accurately fits the description given is a prime number.
