Finding LCM and HCF with Number Blocks
This animation visualizes how to find the Highest Common Factor and Lowest Common Multiple of two numbers using prime factorization trees and grouped blocks. It shows shared and unshared prime factors side by side, illustrating why HCF uses common factors while LCM uses all factors. Useful for middle school students learning number theory and preparing for fraction operations like simplifying and finding common denominators.
