Разложение числа на простые множители C++

C++

#include 
int main() {
    unsigned int n;
    std::cin >> n;
    const unsigned int max = n;
    for(unsigned int i = 2; i*i <= max; )
        if (n % i == 0) std::cout << i << (1 == (n /= i)? "" : "*");
        else ++i;
    if (n > 1) std::cout << n;
    return 0;
}

JavaScript

function fact(num){
	var max=num;	
	var factors ="";
	for(var i=2;i*i 1)factors+=num;
	return factors;
		 
}
alert(fact(Number(prompt("enter a"))))
