10 to the power of 2 is common to all these numbers. Not the answer that I am looking for...

How about this:
All are evenly divisible by nine. Also, 225 is a perfect square (15), 216 is a perfect cube (6), and the others are prime multiples of nine... but these features are not common to the lot.
There are 17 numbers between 150 and 300 that are divisible by nine: 153, 162, 171, 180, 189, 198, 207, 216, 225, 234, 243, 252, 261, 270, 279, 288, 297.
6 squared = 36 6 cubed = 216 3 cubed = 27 36 + 216 - 27 = 225
32 + 63 = 9 + 216 = 225
Least Common Multiple (LCM) for 15 75 45 is 225.
Well, honey, the least common multiple of 225 and 250 is 2250. You see, you take the bigger number, which is 250, and you check if it's a multiple of 225. If it's not, you keep adding 250 until you find a number that is divisible by both 225 and 250. And voilà, there's your least common multiple.
All the numbers are divisible by: 9
