C++实现：

string getResult(long ulDataInput)
{
	string str1,str2;
	long int i=2;

	while(i<= ulDataInput)
	{
		while(ulDataInput % i == 0)
		{
			stringstream ss;
			ss<<i;
			ss>>str2;			
			str1.append(str2).append(" ");

			ulDataInput /= i;
		}
		i++;
	}
	return str1;
}

void main()
{
	string strTarget;
	long n1;
	cin >> n1;
	strTarget = getResult(n1);
	cout << strTarget << endl;
	system("pause");
}
