My friend gave me and some other friends this mathematical puzzle, that I can't even come close to solving:
Can you simplify 3,628,200 in 3 characters?
By "3 characters", he means that you can type the representation of the number in 3 or less characters (bytes don't matter). For example, $3+2$ is 3 characters.
$10!$ is the closest I've gotten, only $600$ away. There are no restrictions, any (previously known) special functions, tricks or underhandedness is completely fine.
