So you guys want to know where I was born II

Seems the previous clue was no challenge for you guys, so let's see if I can make this one a bit more interesting. You're going to work a little bit of math to get this one. The next clue is ciphered and I've used a simple substitution cipher, based on a number (called the key), to write it.

To help you understand what this means, here is an example: suppose you know the key to your cipher is 4, then you would substitute the letter A by the fourth letter in the alphabet, D, the letter B by the fifth letter, E, the C by the sixth letter, F, and so on and so forth. So, instead of, say, HELLO, you would write KHOOR.

Now, for the actual clue:

GUR PBHAGEL JURER V JNF OBEA VF N ERCHOYVP

And to get the key to the cipher: multiple the amount of divisors the number 120 has by the tenth smallest prime number, now add the digits of the result and use that as your key.

Good luck, hopefully you'll get it as fast as the previous one.

ETA: Now, guys, I'm expecting you to solve this on your own, you don't need anybody's help, you'll see :).
