Answer:
24
Explanation:
Anything "factorial" is the result of multiplying the number by itself and all numbers below it, so:
4! = 4 × 3 × 2 × 1 = 24
There's no other info for this question so I assume you just wanted the answer, but as an example of a program here's a function that would work it out for you by using recursion in javascript, to use this you would call factorial(4) like at the bottom:
function factorial(num) {
if (num < 0)
return -1;
else if (num == 0)
return 1;
else {
return (num * factorial(num - 1));
}
}
factorial(4);
