Grinding Aces Math Exam 2025 - Problem 5


For any positive integer n2n\ge 2 let d(n)d(n) denote the number of positive divisor of nn and ϕ(n)\phi(n) denote the number of positive integers from 11 to nn inclusive relatively prime with nn. Let νp(n)\nu_p(n) denote the largest value kk such that pkp^k divides nn. Given that NN is a positive integer for which d(N)=2025d(N)=2025, let the minimum value of ϕ(N)\phi(N) be xx. Find

p is primeνp(x)\sum_{p \text{ is prime}}{\nu_p(x)}
