Ronaldo starred for the reigning European champions in the Group B clash in Vilnius, taking his tally to 93 international goals.
The 34-year-old was happy for his team after the huge win lifted second-placed Portugal onto eight points.
"I'm having a good time, but the team was doing very well too," Ronaldo told reporters.
"I am happy and enjoying this moment, not because I scored the goals, but because of the level we have been able to demonstrate in recent years.
"It is up to me to continue helping the national team."
