$$$120!$$$

Find $$$120!$$$

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, $$$120! = 1 \cdot 2 \cdot \ldots \cdot 119 \cdot 120 = 6689502913449127057588118054090372586752746333138029810295671352301633557244962989366874165271984981308157637893214090552534408589408121859898481114389650005964960521256960000000000000000000000000000.$$$

$$$120!\approx 6.68950291344913 \cdot 10^{198}$$$A
