Determine the total number of triplets (x, y, z) of positive integers, with x ≤ y ≤ z, that satisfy this equation:

1/x + 1/y + 1/z = 7/15

Sometimes, and with the utmost care, an author might successfully edit a problem after it has gone public. 

I can assure you that the text as read is what was made public.  In review I've too often read something too hastily as you apparently did here.



I won't dwell on the edit issue but I will advise should anyone really need that information.
