Abstract
We prove several unique prime factorization results for tensor products of type II1 factors coming from groups that can be realized either as subgroups of hyperbolic groups or as discrete subgroups of connected Lie groups of real rank 1 In particular we show that if mathcalRoverlineotimesmathcalLmathbbF r 1overlineotimescdotcdotcdotoverlineotimesmathcalLmathbbF r m is isomorphic to a subfactor in mathcalRoverlineotimesmathcalLmathbbF s 1overlineotimescdotcdotcdotoverlineotimesmathcalLmathbbF s n for some 2≤r i s j ≤∞ then m≤n
