That's not the factorial of any number. For a start, the factorial of any number greater than or equal to 2 is even, because of the factor 2. The factorial of any number greater or equal to five ends with 0.

I suspect the questioner meant to ask how to write 8*7*6*5*4*3*2*1 as a factorial. If so, then the answer is "8!"
Pseudo code+factorial
#!/usr/bin/perl print factorial($ARGV[11]); sub factorial { my($num) = @_; if($num == 1) { return 1; # stop at 1, factorial doesn't multiply times zero } else { return $num * factorial($num - 1); # call factorial function recursively } }
#include <iostream> using namespace std; int main() { int i, number=0, factorial=1; // User input must be an integer number between 1 and 10 while(number<1 number>10) { cout << "Enter integer number (1-10) = "; cin >> number; } // Calculate the factorial with a FOR loop for(i=1; i<=number; i++) { factorial = factorial*i; } // Output result cout << "Factorial = " << factorial << endl;
factorial number Var num= prompt("enter any number "); Var i=1; Var fact=1; for(i=1;i
// Iterative solution public static final long iterativeFactorial(final long n) { long factorial = 1; for (long i = 1; i <= n; i++) { factorial *= i; } return factorial; } // Recursive solution public static final long recursiveFactorial(final long n) { if (n <= 1) { return n; } return n * recursiveFactorial(n - 1); } // Arbitrary length solution - may take a while, but works on any positive number. public static final BigInteger factorial(final BigInteger n) { BigInteger factorial = BigInteger.ONE; for (BigInteger i = BigInteger.ONE; i.compareTo(n) <= 0; i = i.add(BigInteger.ONE)) { factorial = factorial.multiply(i); } return factorial; }
8! means 8*7*6*5*4*3*2*1=40,320

How do you write an expression
To write a program that calculates the factorial of a number in PHP, you can use a recursive function or an iterative approach. Here’s a simple example using a loop: function factorial($n) { $result = 1; for ($i = 2; $i <= $n; $i++) { $result *= $i; } return $result; } echo factorial(5); // Outputs: 120 This code defines a function that multiplies numbers from 2 up to the given number $n to compute the factorial.
When a factorial is in parentheses, it typically indicates that the entire expression within the parentheses should be evaluated first before applying the factorial operation. For example, (n!) means to first calculate the value of n and then take the factorial of that value. This notation helps clarify the order of operations in mathematical expressions.
