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