# number num = 4 # 'fact' - variable to store factorial fact = 1 # run loop from 1 to num # multiply the numbers from 1 to num # and, assign it to fact variable for i in range(1, num + 1): fact = fact * i # print the factorial print("Factorial of {0} is: {1} "....
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 # Python program to find the factorial of a number provided by the user. # change the value for a...

factorial() function from the NumPy library is actually a function from the maths library of python. It is similar to scipy.math.factorial(). The function computes the factorial of positive numbers. It does not work for input arrays. In order to calculate the factorial of an input array, c...

where n should be greater than 0. There is no factorial defined for negative numbers whereas factorial of 0! is 1. In this tutorial, you will learn how to write a python program to find factorial of any non-negative integer which is greater than 0. ...

It is important not to confuse the factorial with the prime factorization of a number, which is a way of obtaining the prime numbers that, when multiplied together, give your number. Prime factorization has its uses in maths and is arguably more well-known than the n-factorial. Part of the...
Factorial is a function applied to natural numbers greater than zero. The symbol for the factorial function is an exclamation mark after a number, like this: 2!Formulan!=1×2×3...×nn!=1×2×3...×n Where −n!n! = represents factorial nn = Number of setsExample...
nresultiin resultresultiiiend This code is similar to the for loop method but uses a while loop instead. The execution in matlab command window is as follows − >> n = 6; result = 1; i = 1; while i <= n result = result * i; i = i + 1; end >> result result = 720 ...
