Vedclass · Answer

(A) The relationship between two numbers $a$ and $b$ is given by the property: $LCM(a, b)$ must be perfectly divisible by $HCF(a, b)$.Given $HCF(a, b) = 12$.We check each option to see if it is divisible by $12$:$(A)$ $90 / 12 = 7.5$ (Not divisible)$(B)$ $24 / 12 = 2$ (Divisible)$(C)$ $48 / 12 = 4$ (Divisible)$(D)$ $36 / 12 = 3$ (Divisible)Since $90$ is not divisible by $12$,it cannot be the $LCM$.

If $HCF(a, b) = 12$,then which of the following cannot be the $LCM(a, b)$?
