What are prime and composite numbers?
For some students, the topic of prime and composite numbers can be confusing. A prime number is a number that only has 1 and itself as factors. A composite number has other factors besides 1 and itself. For example, the factors of 13 is 1 and 13, so this is a prime number. However, the factors of 8 are 1, 8, 2, 4, so this would be a composite number.
