Prime Factorization Created by Cristina Salas Leal November 16, 2007
Objective • The students will learn to use a factor tree to find the prime factorization of a composite number. • TEKS (6.1D) The student will write prime factorizations using exponents.
Math Journal • Write and answer the following questions in your math journal. • Using only one word, how would you define a prime number? • Using only one word, how would you describe a composite number? • What is prime factorization?
What is Prime Factorization? • Prime factorization breaks down a number into its prime factors.
Prime & Composite • A prime number is a number with exactly two unique factors. • A Composite number is a number with more than two factors.
Factor Tree Step 1: Start with a composite number Step 2: Factor the number Step 3: Continue factoring composite factors Prime Factorization of 12 = 2 x 2 x 3
