How do you find greatest factor of a number which is a factorial number in c language?

Answer 1

#include<stdio.h> #include<conio.h> main() { int f=1,i=1,n; clrscr(); printf("\n Enter factorial value"); scanf("%d",&n); for(;i<=n;i++) { f=f*i; } printf("\n The factorial value=%d",f); getch(); }

Answer 2

To get the factorial of a number, "n", do one of the following:

1) Multiply all numbers from one to "n". To do this, assign the number 1 to the result, then write a loop (from 1 to n) that will multiply result by each of the numbers the loop counter assumes.

2) Another method is to use recursion. If n = 0, return 1; otherwise, the factorial of n is equal to n * factorial(n - 1).

Answer 3

Just try every factorial numbers (1, 2, 6, 24, 120 and so far) whether or not they divide the given number.
