set cardinality

Consider the following sets, where n > 2: S 1 : Set of all n x n matrices with entries from the set {a, b, c} S 2 : Set of all functions from the set {0,1, 2, ..., n 2 — 1} to the...

What is the cardinality of the set of integers $$X$$ defined below? $$X = $$ {$$n\left| {1 \le n \le 123,\,\,\,\,\,n} \right.$$ is not divisible by either $$2, 3$$ or $$5$$ }
