Prime Numbers A prime number is a whole number that has exactly two factors, 1 and the number itself. The number 1 is not considered prime because it does not have exactly two factors. Prime numbers that are between 1 and 20 are 2, 3, 5, 7, 11, 13, 17, and 19. Prime Factorization A composite number can be expressed as a product of prime numbers. This is called the prime factorization of the number. The prime factorization of the composite number 45 is 3 × 3 × 5.

Factor – Factors are numbers you can multiply together to get another number. Factors are a defined set not infinite. Example: 2 and 3 are factors of 6, because 2 × 3 = 6 Greatest Common Factor – the greatest of factors of two or more numbers. Example the greatest common factor of 12, 18 and 30 is 6 PAIR SHAR: What is the GCF of 8, 12, and 20

4
Multiples - he result of multiplying a number by an integer (not a fraction). Multiples are infinite. Example: 12 is a multiple of 3, because 3 × 4 = 12 3, 6, 9, 12…… Least Common Multiple - The smallest whole number greater than zero that is a multiple of two or more numbers. Example: the Least Common Multiple of 3 and 5 is 15, because 15 is a multiple of 3 and also a multiple of 5. Other common multiples include 30 and 45, etc, but they are not the smallest (least). PAIR SHARE: What is the LCM of 8, and 12
