1755
2180
3
585
10 218
a) Explain how you know that each factor
tree is not complete.
b) Copy and complete each factor tree to
determine the prime factorization.

your answer is the frist one

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

(by the way, do you mind marking me as brainliest? i'd greatly appreciate it! mahalo! x3)

hello! just here for points! though i wish i knew!
