Sep 1, 2014 at 10:58 comment added Raphael This problem does indeed seem to admit trivial solutions if there are not too many big elements, and none at all otherwise. Are there no other restrictions, such as minimising the number of pairs in the result?

Aug 31, 2014 at 21:35 comment added Florian F There must be a typo. An array of 180 plus an array of 240 sums to 420. The sum of your items is 785, not a multiple of 420. And all elements are multiple of 15, except for the 5 which is not. You can not use it in a subarray that sums to 180 or 240.
