then 1/(pq) >1 or not..

For N = P^x X Q^y (where P,Q are prime no and N is natural number )Total set of two natural number which have their LCM as N is given by

[(x+1)(y+1) + xy]

Can someone explain why xy term is added? . I understood (x+1)(y+1) is there because If we treat one no = N then for their lcm = N other no should be its factor so total factor = (x+1)(y+1)

Can someone explain why xy term is added?????
