What if \(n>1\) ?

\(\large 2! = 2\times 1= 2 \) which is even.
\(\large 3! = 3\times2\times1 =6 \) which is even.
\(\large 4! = 4\times 3\times 2 \times 1 = 24 \) which is even.
Is it true that \(n!\) is always even for \(n >1\)?

Notation: \(!\) is the factorial notation. For example, \(8! = 1\times2\times3\times\cdots\times8 \).
