Let G be a finite no-Abelian group and Irr(G)be the set of all irreducible charactersof G. In this paper,we consider the set of quotients and investigate howcertain assumptions on these numbers affect the structure of G. For example, suppose is the prime number decomposition of the natural number n. Set and W(G)=max.We show that if G is non-solvable with W(G)=4,then G is exactly one of the following groups: Z_p× A_5, SL(2,5),S_5, PSL(2,7),PSL(2, 11)andPSL(2, 13)。
