Answer:
4! = 24
In other words, 4 factorial is 24.
Because there are 24 ways to arrange 4 objects.
Explanation:
A factorial of a positive integer can be given by
n! = n × (n-1)! = n × (n-1) × (n-2) × ... × 1.
Which is the product of all positive integers less than or equal to n.
Or for any integer, the consecutive product of integers approaching 1.
4! = 4 × (4-1) × (4-2) × (4-3) = 4 × 3 × 2 × 1 = 12 × 2 × 1 = 24 × 1 = 24
