Question 238440: Joe Lucky recently won the New Mexico lottery. The amount of money that he won just happens to be the smallest number of cents (other than 1 cent) that is a perfect square, a perfect cube, and a perfect fifth power. How much money did he actually win?

The key to this problem is to understand the following property of exponents: :- For perfect squares, q = 2: . This tells us that any exponent that is a multiple of 2 is a perfect square.
- For perfect cube, q = 3: . This tells us that any exponent that is a multiple of 3 is a perfect cube.
- For perfect fifth powers, q = 5: . This tells us that any exponent that is a multiple of 5 is a perfect fifth power.
So an exponent that is a prefect square, perfect cube and a perfect fifth power, all at the same time, will be a multiple of 2, 3 and 5. The lowest such exponent will be the Lowest Common Multiple (LCM) of these. The LCM of 2, 3 and 5 is 30.
So the smallest number of cents (other than 1) would be cents which is $10737418.24.
