If X, Y and Z are three numbers, such that LCM of X and Y is X and LCM of Y and Z is Y, then find the HCF of X, Y and Z.
If X, Y and Z are three numbers, such that LCM of X and Y is X and LCM of Y and Z is Y, then find the HCF of X, Y and Z.
Show Hint
If $\text{LCM}(a,b)=a$, then $a$ is divisible by $b$.
Use divisibility chains to quickly find HCF.
