If the highest common factor (H.C.F) of two numbers is 8, which of the following values cannot be their least common multiple (L.C.M)?
Explanation
Since the H.C.F of the two numbers is 8, their L.C.M must be divisible by 8. Among the options, 60 is not divisible by 8, so it cannot be the L.C.M of the two numbers.
