Greatest and Lowest Common Factors

The video tutorial explains the difference between the greatest common factor (GCF) and the lowest common multiple (LCM) using the numbers 12 and 8. It describes how the GCF is the largest number that divides both numbers without a remainder, while the LCM is the smallest number that both numbers divide into evenly. The GCF of 12 and 8 is 4, and the LCM is 24.
