In this program, we've used for loop to loop through all numbers between 1 and the given number num (10), and the product of each number till num is stored in a variable factorial. We've used long instead of int to store large results of factorial.

Sep 10, 2017 · We will write three java programs to find factorial of a number. 1) using for loop 2) using while loop 3) finding factorial of a number entered by user. Before going through the program, lets understand what is factorial: Factorial of a number n is denoted as n! and the value of n! is: 1 * 2 * 3 * …

Apr 7, 2025 · The factorial of a non-negative integer is multiplication of all integers smaller than or equal to n. In this article, we will learn how to write a program for the factorial of a number in Java. Formulae for Factorialn! = n * (n-1) * (n-2) * (n-3) * ..... * 1 Example: 6! == 6*5*4*3*2*1 = 720. 5!

In this tutorial, we shall write Java Program to Find Factorial of a Number using looping statements like for or while loop and recrusion techniques.

Apr 19, 2021 · In this Java program, you’ll learn how to find the factorial of a number in java. We are using a for loop and a while loop for finding the factorial of a number in Java. What is a Factorial Number? In mathematics, the factorial of a positive integer n, denoted by n! is the product of all positive integers less than or equal to n:

Mar 17, 2021 · Java Program to Find a Factorial of a Number Using for loop. Output: In this example, we will calculate the factorial of a number taking the value from the user. You may also learn to find Factorial of a Number in Java Using recursion.

Here is a Java program to find factorial of a number using for loop. Given a positive integer N, we have to calculate factorial of N using for loop. The factorial of a integer n, denoted by n!, is the product of all positive integers less than or equal to n. Factorial does not exist for negative numbers and factorial of 0 is 1.

Apr 24, 2022 · Different Java programs to find the factorial of a number. Learn how to do it by using a for loop, while loop, do-while loop and recursively.

Write a Java Program to find the Factorial of a number using For Loop, While Loop, Functions, and Recursion. The Factorial of a number is the product of all the numbers less than or equal to that number & greater than 0.

To find the factorial of a number, follow these steps: Take a number. Use a variable (fact) initialized to 1 to store the result. Use a Loop to Calculate Factorial: Use a for loop starting from 1 to the given number (n).
