Determine si un número es factorial en Java

// Java implementation for the above approach
class GFG
{
 
    // Function to check if the given number
    // is a factorial of any number
    static boolean isFactorial(int n)
    {
        for (int i = 1;; i++)
        {
            if (n % i == 0)
            {
                n /= i;
            }
            else
            {
                break;
            }
        }
     
        if (n == 1)
        {
            return true;
        }
        else
        {
            return false;
        }
    }
     
    // Driver Code
    public static void main (String[] args)
    {
        int n = 24;
        boolean ans = isFactorial(n);
         
        if (ans == true)
        {
            System.out.println("Yes");
        }
        else
        {
            System.out.println("No");
        }
    }
}
