In N is a positive integer less than 200, and 2N/108 is an integer, then N has how many different positive prime factors?
Choose the correct choice from the following options
A) 2  B) 3  C) 5  D) 6  E) 8
(B).   2n/108 must be an integer. =&gt; n/54 must be an integer. Hence n must be a multiple of 2*3*9.   =&gt; n has 3 different prime integers.
