How many factors of 2475 are odd numbers greater than 1?	Choose the correct option
A) 3  B) 4  C) 17  D) 6  E) 7
prime factors of 330 are 2^1,3^2,5^2 and 11^1   total divisors = (power if a prime factor+1)   total no. of odd factors(3,5,11) = (2+1)(2+1)(1+1) =18   since we need odd divisors other than 1 =&gt;18-1=
