Problem: how many factors of 30 are odd numbers greater than 1 ?
Rationale: "prime factors of 30 are 2 ^ 1,3 ^ 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 b is the answer"
annotated_formula: divide(30, multiply(const_10, const_2))
