C) 11 and 385
D) 22 and 770
Correct Answer: A
Solution :
\[11=11\times 1\] \[1385=11\times 5\times 7\] \[\therefore \]LCM\[=11\times 5\times 7=385\] HCF = 11 \[55=11\times 5\] \[77=11\times 7\] LCM\[=11\times 5\times 7=385\] HCF\[=11\]\[\Rightarrow \]\[(11,385)\]or \[(55,77)\]You need to login to perform this action.
