If g and h are positive integers, and 3 is not a factor of h, then h may be which of the following?
Options:
A) (g−1)·g·(g+1)
B) (g−3)·(g−1)·(g+1)
C) (g−2)·g·(g+2)
D) (g−1)·g·(g+2)
E) (g−3)·(g+1)·(g+2)
Plugged in values :   let g=5   A. (g−1)·g·(g+1) --&gt; divisible by 3   B. (g−3)·(g−1)·(g+1) --&gt; divisible by 3   C. (g−2)·g·(g+2) --&gt; divisible by 3   D. (g−1)·g·(g+2) --&gt; not divisible. Hence the answer.
