Lagrangian:
where the function we want to minimize is actually
, but it's easy to see that 
and 
have critical points at the same vector 
.
Derivatives of the Lagrangian set equal to zero:
Substituting the first three equations into the fourth gives
Solving for
, we get a single critical point at 
, which in turn gives the least distance between the plane and (0, 2, 5) of 
.

Fermat's little theorem states that
≡a mod p
If we divide both sides by a, then
≡1 mod p
=>
≡1 mod 17
≡1 mod 17
Rewrite
mod 17 as
mod 17
and apply Fermat's little theorem
mod 17
=>
mod 17
So we conclude that
≡1 mod 17
If we divide both sides by a, then
=>

So we conclude that
