Apr 8, 2025 · This code calculates the factorial of a number by first finding the prime factors of each number from 2 to n, and then multiplying them together to compute the factorial.

The factorial of a number is the product of all the integers from 1 to that number. For example, the factorial of 6 is 1*2*3*4*5*6 = 720. Factorial is not defined for negative numbers, and the factorial of zero is one, 0! = 1. Factorial of a Number using Loop

Jul 9, 2024 · math.factorial(x) Parameters : x : The number whose factorial has to be computed. Return value : Returns the factorial of desired number. Exceptions : Raises Value error if number is negative or non-integral.

Jan 6, 2022 · How do I go about computing a factorial of an integer in Python? The easiest way is to use math.factorial (available in Python 2.6 and above): If you want/have to write it yourself, you can use an iterative approach: fact = 1. for num in range(2, n + 1): fact *= num. return fact. or a recursive approach: if n < 2: return 1. else:
