$6\times8\times10 \div(2\times2\times2)=60.$ $60=2^{2}\times3\times5$, which means it has $3\times2\times2=12$ factors. 
Vivian bakes a cuboid cake with a dimension of $6\times8\times10$ and cuts it into many small cubical cakes with a dimension of $2\times2\times2$. She wants to equally divide the cake without remainder among $x$ people so that each person can get at least one small cake. How many possible values of $x$ are there? 

(a) $$6$$ 
(b) $$8$$ 
(c) $$12$$ 
(d) $$16$$ 
(e) $$18$$
