[?] Avoid 'protected' warnings?

Questions
1

Was working some training problems and solved this one as below: Verify GCD[x] * LCM[y] = x * y for 74613 and 85085.

In[22]:= (GCD[x, y] * LCM[x, y] = x * y) /. {x -> 74613 , y -> 85085}

During evaluation of In[22]:= Set::write: Tag Times in GCD[x,y] LCM[x,y] is Protected.

Out[22]= 6348447105

How should I rewrite this solution so as to avoid the warning?

Have a look at the difference of =, ==, and ===

== works. Thanks you.
