A local dentist wants to know how many adults in a town receive regular cleanings. The dentist surveys 120 random adults living in the town and found 84 people receive regular cleanings. If there are 8,500 adults in the
town, how many can be expected to receive regular cleanings?

aloha~! my name is zalgo and i am here to you out on this amazing day. to answer your question, yes, nonzero numbers can have a greatest common factor and that would be 1. still don't get it? let me considering every number is divisible by 1 and hence every number has 1 as a factor of theirs. so, if 2 nonzero numbers didn't share any gcf (greatest common factor), they would still have a factor in common and that would be 1.

i hope that this ! : p
