The tutorial starts with an introduction to **Multiples, Factors, Prime Numbers and Prime Factorization including LCM and GCF** and is then followed with a list of the separate lessons, the tutorial is designed to be read in order but you can skip to a specific lesson or return to recover a specific math lesson as required to build your math knowledge of **Multiples, Factors, Prime Numbers and Prime Factorization including LCM and GCF**. you can access all the lessons from this tutorial below.

In this Math tutorial, you will learn:

- What are multiples of a number?
- What are factors of a number?
- How to find the factors of a number?
- What are prime numbers? What do we call a number that is not prime?
- How to write a number as a product of prime factors?
- Why is the least common multiple of two or more numbers so important?

- How are these two concepts (LCM and GCF) applied in practice?

A store only sells forks in sets of 6 and not individually (single pieces). How many sets should you buy if 48 people are invited for dinner? What about if there were 78 people?

Can you buy exactly 33 forks in the above store? Why? What must you do in this example?

Sets of plates have 12 pieces. How many sets from each type (forks & plates) are needed for 48 people? Is there a smaller number in which every person invited has one fork and one plate?

This tutorial will focus on multiples and factors of a number as well as the common multiples and factors of two or more numbers. The thing that interests us most is the smallest of multiples and the greatest of factors as these two factors have a wide range of applications in practice.

In addition, we will explain prime numbers and how to write a number in prime factors.
