- Recognize even and odd numbers
- Define prime numbers
- Find the greatest common factor and the least common multiple between a set of numbers
- Be able to identify which numbers are divisible by 2-10
The chapter's short video lessons have an available transcript in case you feel like reading the material. Use the quizzes at the end of the chapter to ensure that you have a firm grasp on the subject.
1. How to Identify Even & Odd Numbers
In this short lesson, you will learn a bit more about numbers. You will learn what makes a number even, what makes a number odd, and how to identify each.
2. What Are Prime Numbers? - Definition & Examples
In this lesson, we'll do a brief review of factors, and then learn how factors make prime numbers unique. You can also test your knowledge with a brief quiz.
3. How to Find the Greatest Common Factor
If the factors of a number are the different numbers that you can multiply together to get that original number, then the greatest common factor of two numbers is just the biggest one that both have in common. See some examples of what I'm talking about here!
4. How to Find the Least Common Multiple
The least common multiple of two numbers is the smallest number that can be divided evenly by your two original numbers. See some examples of what I'm talking about here!
5. Divisibility by 2, 3, and 4
In this video lesson, you will learn what it means to be divisible. Also, you'll see what numbers are divisible by 2, 3, and 4. You will also learn how you can check if something is divisible by these numbers.
6. Divisibility by 5, 6, and 7
In this video lesson, we will see what numbers can be divided equally by 5, 6, and 7. Learn the pattern that you can use to find other numbers divisible by 5, 6 and 7. Learn how you can visualize divisibility.
7. Divisibility by 8, 9, and 10
In this video lesson, we will see what numbers are divisible by 8, 9, and 10. You will learn how you can figure out these numbers yourself. Learn what it means to be divisible.
