## Re: Help with LCM and GCD.

Well it depends:

$\displaystyle \text{If }a=5,~b=5~\&~c=5\text{ then GCD}(a,b,c)=~?$

$\displaystyle \text{If }a=5,~b=5~\&~c=10\text{ then GCD}(a,b,c)=~?$

$\displaystyle \text{If }a=5,~b=10~\&~c=15\text{ then GCD}(a,b,c)=~?$

The point being the answer is $\displaystyle \min\{a,b,c\}$.
