If another question asks for LCM of n and 6 to be a really large number, take note n cannot have (2 x 3) in its expression as "n" obtained will have a lower LCM than what the question indicates

E.g for this question
Lets say n = 2x2x3 = 12
But LCM of 6 and 12 is 12 since 6 is a multiple of 12, although 24 is also a common multiple of 6 and 12
