Lesson 4-1 Pages Factors and Monomials

What you will learn! 1. How to determine whether one number is a factor of another. 2. How to determine whether an expression is a monomial.

FactorsDivisible Monomial

What you really need to know! Two or more numbers that are multiplied to form a product are called factors. Any number is divisible by its factors. The following rules can be used to determine mentally whether a number is divisible by 2, 3, 5, 6, or 10.

What you really need to know! A number is divisible by: 2 if the ones digit is divisible by 2. 3 if the sum of the digits is divisible by 3. 5 if the ones digit is 0 or 5. 6 if the number is divisible by 2 and by if the ones digit is 0.

Example 1: Determine whether 435 is divisible by 2, 3, 5, 6, or NO 3YES 5YES 6NO 10NO

Example 2: Sonya is running for student council president. She wants to give out campaign flyers with a pen to each student in the school. She can buy “Vote for Sonya” pens in packages of 5, 6, or 10. If there are 306 students in the school and she wants no pens left over, which size packages should she buy? She should buy pens in packages of 6.

Example 3: List all the factors of x 64 2 x 32 4 x 16 8 x 8 1, 2, 4, 8, 16, 32, 64

Example 4: Determine whether each expression is a monomial. 4(n + 3) 4n + 12 No! It has two terms.

Example 5: Determine whether each expression is a monomial. Yes! It has one term.
