Get the number whose factorial is to be calculated. Here we discuss the basic concept and how to find the factorial of a number in PHP with different examples. Write a PHP program to find factorial of a number using recursive function. But the ring of formal power series over a factorial ring need not be factorial. In the following PHP program factorial of number 5 is calculated. } 'The factorial of the number '.$input.' . return (factorial)} Output: findfactorial(0) [1] 1 findfactorial(3) [1] 6. } function Factorial_Function($input) Python program to find factorial of a number using while loop. Within this function if the input is greater that one, then the same function is called again and if the input is less than or equal to 1 then one is returned. The factorial of 0 is always 1 and the factorial of a negative number does not exist. The factorial of a number is the product of all integers up to and including that number, so the factorial of 4 is 4*3*2*1= 24. ?> The factorial of a number is the product of all integers up to and including that number, so the factorial of 4 is 4*3*2*1= 24. This is a simple program using for loop. A Simple Solution solution is to initialize sum as 0, then run a loop and call factorial function inside the loop..
