$$$16!$$$

Find $$$16!$$$

The factorial of a positive integer $$$n$$$ is the product of all positive integers less than or equal to $$$n$$$: $$$n! = 1 \cdot 2 \cdot \ldots \cdot (n-1) \cdot n$$$.

Thus, $$$16! = 1 \cdot 2 \cdot \ldots \cdot 15 \cdot 16 = 20922789888000$$$.

$$$16! = 20922789888000$$$A
