Mr. Chen is painting one wall of a room in his attic. He needs to determine the area of the wall so he will know how much paint he will buy. The drawing below shows the dimensions of the wall. If one quart of paint will cover 16 square centimeters, how many whole quarts will Mr. Chen need to buy?

He will need to buy whole quarts.

your answer would be 12

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
