Factorial of a number is obtained from the result of multiplying a series of descending natural numbers. To find factorial of a number in c programming language we need to use for loop and iterate from n to 1 ; in side loop we need to write a logic to multiply the result. For example n=5 then factorial of 5 will be 1*2*3*4*5= 120. Step 2: Initialize F=1. In the above program, the user is prompted to enter a number. Divide the number by 25 to find out how many times 25 are present in a number as it will add extra 5 to number then, Divide the number by 125 to find out how many times 125 are present in a number as it will add extra 5 to number and so on. Below program takes a number from user as an input and find its factorial. So if you see something like 5! Java Factorial : Iterative approach The following algorithm generates factorial of a number using a while loop. In mathematics, the factorial of a non-negative integer n, denoted by n!, is the product of all positive integers less than or equal to n. For example, 5! public program to find factorial of any number in java, Factorial of 5 = 120. Computing a factorial is of course expansive. In this article, we will discuss different ways to find factorial of a number in Java. This Program prompts user for entering any integer number, finds the factorial of input number and displays the output on screen. Write a JavaScript program to calculate the factorial of a number. We can find factorial of such numbers using BigInteger class defined in java.math package. Algorithm 1. A Krishnamurthy number is a number whose sum of the factorial of digits is equal to the number itself. Write a C Program to find factorial by recursion and iteration methods. Write an algorithm an draw flowchart to find factorial of ... ... / Because factorial of 50 has almost 60 digits. And also factorial … = 5 x 4 x 3 x 2 x 1 = 120. = n * n – 1! is pronounced as "4 factorial", it is also called "4 bang" or "4 shriek". Step 2: Enter the value of N. Step 3: Check whether N>0, if not then F=1. Step 7: Now print the value of F. The value of F will be the factorial of N(number). This is the C program code and algorithm for finding the factorial of a given number. ‘N’ multiplied by ‘N-1’ multiplied by ‘N-2’ and so on till ‘1’. is O(k log k) and the number of bits used to represent k is O(log k). by k. The number of bits used to represent (k-1)! From value, A up to 1 multiply each digit and store 4. The same could be … In this tutorial, we are going to write a java program which takes an input and print factorial of a number.
