How many factors of 60 are odd numbers greater than 1? Options.
A) 3 B) 4 C) 5 D) 3 E) 7

Rationale: prime factors of 60 are 2 ^ 2,3 ^ 1,5 ^ 1 total divisors = ( power if a prime factor + 1 ) total no . of odd factors ( 3,5 , ) = ( 1 + 1 ) ( 1 + 1 ) = 4 since we need odd divisors other than 1 = > 4 - 1 = 3 odd divisors d is the answer
Answer: D
