Atechnician charges an initial fee of $300 plus an hourly fee of $60. mr. jenks paid the technician $480. how many hours did the technician work?

3 hours

subtract the initial fee from the payment

$ 480 - $300 = $180

divide $180 by $60 = 3 hours

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
