The Great Plains.
Least common, most likely you mean lowest common multiple? If it is lowest common multiple (LCM) then it is 75. This can be worked out from the prime factors excluding duplicates where the prime factors are the same. I.E. 3*5*5 = 75 In this case there are no common prime factors so you could just as easily do 3*25 Hope this helps
