My math teacher gave the class the following problem"

What is the first prime number that works in the above?"

I did it by writing a Liberty Basic computer program. 
You have to go to the 1245th prime, which is 10141,
before the product exceeds 10.

matrix%281%2C7%2C%281%2B1%2F2%29%281%2B1%2F3%29%281%2B1%2F5%29%281%2B1%2F7%29%281%2B1%2F11%29%2C%27...%27%2C%281%2B1%2F10141%29%2C+%27=%27%2C+10.0008518%2C+%27%3E%27%2C+10+%29

So the answer is that 10141, which is the 1245th prime, is the
smallest prime number such that the product exceeds 10.
