 General Observation | Comment 5 of 6 |

While I would not like to respond to the comments received so far at this early stage, I wish  to point out that without the "smallest" restriction, there is at least one other set  (1080, 1260, 1512, 1818, 1890) that satisfies  conditions of Part -2, since:

1080 + 1260 + 1512 + 1818 + 1890 = 7560 and 7560 is divisible by each of 1080, 1260, 1512 and 1890 ( with the exception of 1818)..

I may add that this problem also possesses an analytic solution and look forward to comments from members in that direction.
