#### HCF LCM Venn Diagram

Description

The Lowest Common Multiple (LCM) is the smallest positive number that is a multiple of two or more numbers.

For example the LCM of 4 and 6 is 12 because

Multiples of 4 are 4, 8, 12, 16, 20….

Multiples of 6 are 6, 12, 18, 24…

12 is the first number in both lists.
