A three digit number "abc" has the property that the product of a and b is equal to c. The digits a, b, and c are not necessarily distinct. What is the greatest possible value of the three digit number?

 

And also this:

 

Some perfect squares (such as 121) have a digit sum  that is equal to the square of the digit sum of their square root , and .

What is the smallest perfect square greater than 100 that does not have this property?
