((180045)/5)=36009  ((36009)/3)=12003  ((12003)/3)=4001=prime  ⇒180045=3^2 ×5×4001    number of divisors from 180045:  (2+1)(1+1)(1+1)=3×2×2=12

if N=p_1 ^a_1  .p_2 ^a_2  .p_3 ^a_3  …p_n ^a_n  ;  p_(1,2,3...) are prime  then, d(N)=Π_(i=1) ^n (a_i +1)  d(N) is a function which tells no. of divisers
ifN=p1a1.p2a2.p3a3pnan;p1,2,3areprimethen,d(N)=ni=1(ai+1)d(N)isafunctionwhichtellsno.ofdivisers

Kunal: you should use N for the number  and n for the number of different primes.  Otherwise it is confusing.
Kunal:youshoulduseNforthenumberandnforthenumberofdifferentprimes.Otherwiseitisconfusing.
