Finding the GCF or greatest common factor of 2 or 3 numbers is as easy as ABC. Watch this video on finding the greatest common factor (GCF) using the prime factorization method. The stepbystep process of drawing prime factor trees, finding the common factors, and multiplying them to figure out the GCF of 2 and 3 numbers is vividly explained with solved examples. A reallife GCF application problem is included to emphasize the relevance of this math concept. Remember, GCF has two other names the Highest Common Factor (HCF), and the Greatest Common Divisor (GCD).
