Lesson 2: Breaking down natural numbers

Here is a PDF version of the lesson.

Here is a PDF version of the workbook containing lots of practice.

Numbers can be broken down into smaller numbers or themselves and 1.

In this lesson we are learning about prime factors, how to determine them and why we need them.

Prime factors are numbers that cannot be split further into other whole numbers, other than themselves and 1.

Factors in general are numbers that the given number can be divided by. 

For example, the factors of 8 are 1, 2, 4, 8.

In this lesson we are also discussing the concept of the Greatest Common Factor for the given two numbers. The GCF is the largest number the two given numbers could be divided by.

The Least Common Multiple is the smallest number that could be divided by the given two numbers. 

For example, the LCM of 4 and 8 is 8, because it could be divided by both 4 and 8 and it is the lowest possible value.
