Determine whether each of these sets is countable or uncountable. for those that are countably infinite, exhibit a one-to-one correspondence between the set of positive integers and that set. • all bit strings not containing the bit 0. • all positive rational numbers that cannot be written with denominators less than 4. • the real numbers not containing 0 in their decimal representation. • the real numbers containing only a finite number of 1s in their decimal representation.

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
