5900f4771000cf542c50ff89 5 false Problem 266: Pseudo Square Root 301915

Description

The divisors of 12 are: 1,2,3,4,6 and 12. The largest divisor of 12 that does not exceed the square root of 12 is 3. We shall call the largest divisor of an integer n that does not exceed the square root of n the pseudo square root (PSR) of n. It can be seen that PSR(3102)=47.

Let p be the product of the primes below 190. Find PSR(p) mod 1016.
