Detailed Solution

Given,
HCF of 306 and 657 is 9.
We know,
For two numbers p and q,
LCM (p, q) × HCF (p, q) = p × q
We get,
LCM(306,657)×HCF(306,657)=306×657 ⇒LCM(306,657)×9=306×657 ⇒LCM(306,657)= 306×657 9 ⇒LCM(306,657)=22338  
Therefore, the LCM (306, 657) = 22338
Hence, the correct option is 1.
