Assuming s1, s2, s3....s7 are the seven sets of strings you have, you may try following logic.
  
String s2_str=String.join(new List<string>(s2),';');
String s3_str=String.join(new List<string>(s3),';');
String s4_str=String.join(new List<string>(s4),';');
String s5_str=String.join(new List<string>(s5),';');
String s6_str=String.join(new List<string>(s6),';');
String s7_str=String.join(new List<string>(s7),';');

Set<String> commonStrings=new Set<String>();
for(String s:s1){
	if(	s2_str.contains(s)	&&
		s3_str.contains(s)	&&
		s4_str.contains(s)	&&
		s5_str.contains(s)	&&
		s6_str.contains(s)	&&
		s7_str.contains(s)
	)
		commonStrings.add(s);
}
