 From primes to palindrome (Posted on 2012-03-24)
The product of the first X primes divided by Y results in a non-trivial (more than a single digit) palindrome number.
Find a solution(or solutions?) for integers X and Y.

 Submitted by Ady TZIDON Rating: 5.0000 (2 votes) Solution: (Hide) Jer: To find X and Y for a given number just factor the number. X is the number of primes up to the largest factor. Y is the product of the missing primes. For example 66 = 2*3*11 The primes up to 11 are 2,3,5,7,11 so there are X=5 primes, the missing ones are 5 and 7 so Y=35. see also CHARLIE'S & DejMar's posts.
