Firstly ->
GCD*LCM=product of integer is applicable to only a pair of 2 integers.
So incase of 3 integers this property does not hold true.

Secondly -> All the integers must be divisible by the GCD.
Hence D is always true.

x,y,z are all divisible by X
GCD is the greatest common divisor hence x,y,z must be divisible by X
its not a 700 level question
