There is one question: Prove that 33 ! is divisible by 2^15. What is the largest integer n such that 33! is divisible by 2n?

latest answer

In terms of prime factors 33! can be written as 2^a ⋅ 3^b 5^c ⋅ 7^d … (33!)=33/2+33/2^2+33/2^3+33/2^4+33/2^5 =16+8+4+2+1=31 Hence, the exponent of 2 in 33! is 31. ∴ Largest value of n is 31.
