Write a program that asks the user to enter an integer X between 1 and 10,000,000. If the user enters an integer not in the range or something other than an integer give an error message and re prompt the user to enter an integer between 1 and 10,000,000 until he enters an appropriate integer.

After the user enters an appropriate integer, your program should find and print the closest Highly Composite Number (Anti-prime Number) to this integer.

If the entered integer X is a Highly Composite Number itself print X.
