Arithmetic Product Puzzle (Posted on 2015-08-13) Difficulty: 3 of 5
Determine the smallest positive integer that is expressible as the product of three distinct positive integers in arithmetic sequence in precisely two ways.

What are the next two smallest positive integers with this property?

**** As an example, 105 is expressible as the product of three positive integers (3, 5 and 7) in arithmetic sequence in only one way as no other positive integer triplet in arithmetic sequence multiplies to 105.
