Let 'n' be a positive integer and P1,P2,.....,Pn be 'n' prime numbers larger than 3 such that [(P1)^2+(P2)^2+........+(Pn)^2] is divisible by 6. The largest integer by which 'n' will always be divisible is ? Official CL Answer is '6' by using (6k+1 or 6k-1) for each Pi and then adding the squares. But I feel the answer should be '2' because if I take 'n'=2 and then take P1=5 and P2=7 then I will get (P1)^2 + (P2)^2= 60 which is divisible by 6 and '2' is not divisible by '6'. Someone please explain where is my logic going wrong. Thanks a lot.
