If you a referring to some thing being powerful because of numerology, you should go to myths and superstitions. This is science and math.

Your definition is incomplete. For 120 to be a powerful number, EVERY prime that divides it must also have the prime² divide it, and while 120/3 = 40, 120/9 is not an integer. According to the links, powerful numbers are the products of a square and a cube. So 121 is powerful, since 121/11 is an integer and 121/11² = 1; 11² • 1^3 = 121 as well.

120 is a very powerful number. I will not sit here and have you bash the number 120.
There are 120 seconds in 2 minutes, 120 minutes in 2 hours. That's 2 episodes of 24.

The number 120 is splitted in factors as follows:
120 = 2*2*3*5*2 = 2*2*2 *3 *5 = 2^3 * 3 * 5 = 2^3 * 15
The Square Root (sqrt) of 120 is:
sqrt (120) = sqrt( 2^3 * 15 ) = sqrt ( 2^3 ) * sqrt(15)
= 2 * sqrt (2) * sqrt(15) = 2 * sqrt(30)
Finally,
sqrt (120) = 2 * sqrt(30)

Without a definition of powerful, this is a very hard thing to prove or disprove. Give us an idea of what you mean....
On an esoteric note, aren't all numbers powerful?
