Find

find all possible integers N satisfying the following properties:
(i) N has atleast two prime factors, and
(ii) N = d12 + d22 + d32 + d42 , where d1, d2, d3, d4 are the first four positive divisors of N

d12 means 12th +ve divisor and so on

i read about some of this fn in some book (probably pi fn ot phi fn) but am not sure
but after 12th,22nd and it is tough 4 me
