Question

How are the processes for finding the least common multiple (LCM) and greatest common factor (GCF) of a set of numbers the same, and how are they different?

Answer 1

GCF is when you have a set of numbers that a common factor such as 27 and 45 the GCF is 9. (9 * 3 and 9 * 5)

LCM is when you have a set of numbers that reach the same answer such as 10 and 18 the LCM is 90 (18 * 5 = 90 and 10 * 9 = 90)

Hope this helps
