Question: A cyber-resilience consultant in Toronto is modeling secure key rotation intervals and observes that a system updates its encryption key every \( k \) hours, where \( k \) is the smallest positive integer such that \( k \equiv 3 \pmod5 \), \( k \equiv 4 \pmod7 \), and \( k \equiv 2 \pmod9 \). What is the value of \( k \)? - Crosslake
