## How do you find the factorial without recursion?

Program #1: Write a c program to print factorial of a number without using recursion.

1. int n, i;
2. unsigned long long factorial = 1;
3. printf(“Enter a number to find factorial: “);
4. scanf(“%d”,&n);
5. // show error if the user enters a negative integer.
6. if (n < 0)
7. printf(“Error! Please enter any positive integer number”);
8. else.

How do you find the factorial of a number in Java?

Factorial Program using loop in java

1. class FactorialExample{
2. public static void main(String args[]){
3. int i,fact=1;
4. int number=5;//It is the number to calculate factorial.
5. for(i=1;i<=number;i++){
6. fact=fact*i;
7. }
8. System.out.println(“Factorial of “+number+” is: “+fact);

Is it possible to find the factorial of a given number without using any loop or recursion ?( Written code?

Sure. As long as n is a natural number, this will return the factorial. The result won’t be exact except for small values of n, but then factorial grows very quickly.

### How do you find the factorial of a number using recursion and iteration in Java?

Find factorial of number in java – recursive & iterative (example…

1. 0! =
2. 1! =
3. 3! = 3 * 2 * 1 = 6.
4. 6! = 6 * 5 * 4 * 3 * 2 * 1 = 120.
5. n! = n * n – 1! = n * n – 1 * n – 2 ! and so on.

How do you find the factorial of a number?

To find the factorial of a number, multiply the number with the factorial value of the previous number. For example, to know the value of 6! multiply 120 (the factorial of 5) by 6, and get 720.

Is there factorial in Java?

BigIntegerMath factorial() function | Guava | Java The method factorial(int n) of Guava’s BigIntegerMath class is used to find the factorial of the given number. It returns n!, that is, the product of the first n positive integers. Exceptions: This method throws IllegalArgumentException if n < 0.

## What is factorial algorithm?

Algorithm of this program is very easy − START Step 1 → Take integer variable A Step 2 → Assign value to the variable Step 3 → From value A upto 1 multiply each digit and store Step 4 → the final stored value is factorial of A STOP.

How do you find factorial easily?

To find the factorial of a number, multiply the number with the factorial value of the previous number. For example, to know the value of 6! multiply 120 (the factorial of 5) by 6, and get 720. For 7!
