# Factor Divisibility

You are given that the equation \( 81x+y=5130 \) where *x*,*y* are nonnegative integers has 64 solutions, from \( (x_{1},y_{1}) \) to \( (x_{64},y_{64}) \). Let \( f(n) \) denote the number of factors of *n* which are divisible by 3 and \( g(n) \) denote the number of factors of *n* which are not divisible by 3. What is \( \displaystyle\sum_{i=1}^{64} \dfrac{f(y_{i})}{g(y_{i})} \)?
