\(n!\) or \(n\)-factorial is the product of all integers from \(1\) up to \(n\) \((n! = 1 \times 2 \times 3 \times ... \times n)\). Let's denote \(n!!\) be the product of all factorials from \(1!\) up to \(n!\) \((n!! = 1! \times 2! \times 3! \times ... \times n!)\). Find the maximum integral value of \(k\) such that \(2014^k\) divides \(2014!!\)
