# Check if a given number is factorial of other

Here given code implementation process.

```
// C program
// Check if a given number is factorial of other
#include <stdio.h>
//Check whether given number is factorial of any number
void is_factorial_of(int num)
{
int result = 0;
if (num == 1 || num == 0)
{
result = 1;
}
else if (num > 1)
{
//Define loop controlling variable
int temp = num;
int i = 1;
// Execute loop, until number is divisible by [i]
while (temp % i == 0)
{
temp = temp / i;
// Get next number
i++;
}
if (temp == 1)
{
//When remainder of (i-1) is one

}
}
