What is algorithm write algorithm for find factorial of a given number?
Step 1: Start Step 2: Declare Variable n, fact, i Step 3: Read number from User Step 4: Initialize Variable fact=1 and i=1 Step 5: Repeat Until i<=number 5.1 fact=fact*i 5.2 i=i+1 Step 6: Print fact Step 7: Stop.
How do you find 20 factorial?
Answer: The factorial of 20 is 2432902008176640000. The Factorial of n is denoted by n!
What is algorithm for factorial program in C?
Algorithm of C Program for Factorial Ask the user to enter an integer to find the factorial. Read the integer and assign it to a variable. From the value of the integer up to 1, multiply each digit and update the final value. The final value at the end of all the multiplication till 1 is the factorial.
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.
What is the algorithm for finding the greatest of three numbers?
Algorithm to find greatest number of three given numbers Read the three integer values in num1, num2, and num3 (integer variables). Check if num1 is greater than num2. If true, then check if num1 is greater than num3. If true, then print ‘num1’ as the greatest number.
How many zeros does 20 factorial have?
4 zeroes
20! has 4 zeroes and so on. An extra zero is created every time a 2 and 5 combine. Every even number gives a two, while every fifth number gives us a 5. Now, the critical point here is that since every even number contributes at least a 2 to the factorial, 2 occurs way more frequently than 5.
What is the largest factorial ever calculated?
170
The largest factorial ever calculated is 170.
How do you find the factorial algorithm?
Factorial Program In C
- 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.
- Pseudocode.
- Implementation.
- Output.
