The greatest common factor (abbreviated GCF) is the largest common factor .Now we define the least common multiple (abbreviated LCM) as the smallest common multiple of two different numbers. Greatest common factor: is abbreviated as GCF. GCF can only be determined for a set of numbers consisting of two or more numbers.For example: What is the LCM of two numbers 30 and 48 if its GCD is 6. Many times, students are asked to find the greatest common factor (GCF) and the least common multiple (LCM) of two or more positive integers to demonstrate their understanding of factors, multiples, and prime factorization. Full Answer.

To find the GCF and LCM, using an example is appropriate. If the two numbers are 3000 and 2500, finding the prime factorizations is the first step.So the GCF is 500 and the LCM is 15,000, meaning the difference between GCF and LCM is 1,000.
