$\small\color{black}\boxed{\colorbox{green}{ Verified answer}}$

HCF of 136, 170, and 255 is 17

---------------------------------------------------------------------

HCF of 36 and 42 is 6

-----------------------------------------

Answer: The prime factorization of 45 is 5 x 3 x 3. The prime factorization of 60 is 2 x 2 x 3 x 5. Therefore the HCF (highest common factor) of these two numbers is the set of factors that appear in both: that's one 3 and one 5.
