65 is a composite number.
A prime number is defined as a natural number greater than 1 that has no positive divisors other than 1 and itself. In contrast, a composite number has more than two positive divisors.
To determine if 65 is a prime or composite number, we can look for its divisors. The number 65 can be divided by 1, 5, 13, and 65. Since it has divisors other than 1 and 65 (specifically, 5 and 13), we classify it as a composite number.
Therefore, 65 is not prime because it can be factored into 5 and 13, which are both positive integers that divide evenly into 65.
