In this video I demonstrate, with the use of prime number trees and a venn diagram, how to find the greatest common factor of two numbers. This video is perfect for students currently studying prime numbers in GCSE maths.
If you'd like to find out how to derive the lowest common multiple of 2 numbers, please watch my previous video: https://youtu.be/ol5GINnBs5I?si=aIbn7_j2aD5sMhPZ

In this video I show you how to find the probability of getting a 7 when rolling two dice and adding up their values, using Open Office Calculator. The same procedure in this tutorial can be used to shortcut your way to solutions to various probabilistic problems.
