Here, we are going to implement logic to find factorial of given number in Python, there are two methods that we are going to use 1) using loop and 2) using recursion method.
Define Factorials. Factorials synonyms, Factorials pronunciation, Factorials translation, English dictionary definition of Factorials. n. The product of all the positive integers from 1 to a given number: 4 factorial, usually written 4!, is equal to 24 .
In the above program, we created two functions factorial() and main(). The factorial() function is a recursive function, which is used to calculate the factorial of the given number.In the main() function, we called the factorial() function and printed the result....

The factorial of a given natural numbernis the product of all the natural numbers less than or equal ton. The factorial ofnis denoted usually byn!Thus, n!= 1 × 2 × ... ×n For largenan approximate expression for n! is given by Stirling’s formula. The number of permutations ofnthin...
factorial of a number calculator - formula, step by step calculation & solved example problems online to calculate the factorial of a given number (positive integer) n. Product of all positive integers n! = n x (n - 1) x (n - 2) x ... x 1.
int fac (int n) { if (n < 0) return -1; //n must be positive if (n <= 1) return 1; return n * fac (n-1); } n <= 1 will be the condition to exit our recursion. Let's say n is 3. We get 3 * fac (2), but 2 is also bigger than one, so we get 3 * 2 ...
