1. OBJ: to write the prime factorization of a number.

2. Factors Whole numbers that can divide evenly into whole numbers. Write all the factors of the number. 30 31 45 87 24

3. Prime or Composite Prime – a whole number that is greater than one and has exactly two whole number factors, 1 and itself. Composite – a whole number that is greater than one and has more than two whole number factors. Tell whether each number is prime or composite. 32 59 83 56 1

4. Prime Factorization When you write a number as a product of its prime numbers. You can use a diagram to help you which is called a factor tree. Find the prime factorization of the following numbers. 32 56 175 180 420

5. Factoring Monomials Monomial – a number, a variable, or the product of a number and one or more variables raised to whole number powers. To factor a monomial, write the monomial as a product of prime numbers and variables with exponents of 1. Factor the monomials. 6ab 15n 3 3x 3 y 2 36s 4 t

6. Assignments Create your own factor tree. Practice W.S. 4.1 B all problems.
