Using Exponents

Finding Factors for a Number  Remind students that a prime number is a number with exactly 2 factors, 1 and itself, and a composite number is a number that has more than 2 factors.  Whole numbers that are multiplied to find a product are called factors of that product.  A number is divisible by its factors. For example, 4 and 2 are factors of 8 because 4 · 2 = 8, and 8 is divisible by 4 and by 2

Finding Prime Factorization of a Number: Explore Activity One

Using a Ladder Diagram  A ladder diagram is another way to find the prime factorization of a number.  Use a ladder diagram to find the prime factorization of 132. Step by Step  Write 132 in the top “step” of the ladder.  Choose a prime factor of 132 to write next to the step with 132.  Choose 2. Divide 132 by 2 and write the quotient 66 in the next step of the ladder.  Now choose a prime factor of 66. Write the prime factor next to the step with 66.  Divide 66 by that prime factor and write the quotient in the next step of the ladder.  Keep choosing prime factors, dividing, and adding to the ladder until you get a quotient of 1.
