Finding Factors and Common Factors

The video tutorial by Amazon Kumar explains how to find common factors and the greatest common factor (GCF) of two numbers, 30 and 18, using a Venn diagram. It begins with an introduction to the concept of common factors and the use of Venn diagrams. The tutorial then details the process of finding factors for each number separately. After listing the factors, the video demonstrates how to use a Venn diagram to visually identify common factors. Finally, it explains how to determine the greatest common factor from the identified common factors, concluding with a summary of the steps involved.
