What is the GCF and LCF of 15 36 42?

Answer 1

Well, darling, the Greatest Common Factor (GCF) of 15, 36, and 42 is 3. As for the Lowest Common Factor (LCF), I hate to break it to you, but that term doesn't exist in mathematics. Maybe you meant the Least Common Multiple (LCM), which would be 252 for these numbers. Hope that clears things up for you, sugar!
