Quizplus · Accepted Answer

A composite number is a positive integer that has at least one divisor other than 1 and itself. 36 has more divisors than just 1 and itself (2, 3, 4, 6, 9, 12, 18), making it a composite number. 23, 13, and 7 are all prime numbers because they only have 1 and themselves as divisors. A composite number is a positive integer greater than 1 that is not prime, meaning it has at least one positive divisor other than 1 or itself. 36 has divisors 1, 2, 3, 4, 6, 9, 12, 18, and 36, making it a composite number. 23, 13, and 7 are all prime numbers as they have only 1 and themselves as divisors.
