10800 write this as the product of different powers of primes
say you get 210 x 34 x 512
then the answer will be
(10+1)(4+1)(12+1)
so taking one of the factors will yield the other.. hence the answer will be
[ {(10+1)(4+1)(12+1)+1}/2 ]
[.] stands for the greatest integer....
i leave the last expresisonto be understood by you :)
