In this section, we learn the basic definition for a prime and a composite number. A prime number is a whole number larger than one that is only divisible by itself or one. Some examples would be: 2, 3, 5, 7, 11, and 13. A composite number is a whole number larger than one, that is divisible by some number other than itself or one. Some examples would be: 4, 6, 8, 9, 10, and 12. Additionally, we learn how to factor a whole number into the product of prime numbers using something known as a factor tree. This is known as finding the prime factorization of a whole number.
