 Strange divisibility (Posted on 2005-05-25)
Without evaluation of it, prove that the number N = 27,195^8 - 10,887^8 + 10,152^8 is divisible by 26,460.

Note: the original problem mistakenly listed the last number as 26,640. This has been corrected

As Richard points out in the solution queue, pcbouhid's proposed official solution claims that 2^2×3^2×5×7^2=26,640, when in fact it's 26,460.

I don't think it calls for removal of the problem, but just consider it, as it can't be changed now, as actually asking to determine the divisibility rather than prove it divisible.  That determination has been made in the comments.
