Nettet10. jan. 2024 · If a number is a sum of 3 squares, it cannot be of the form 4 a ( 8 b + 7) Proof : Suppose, N = 4 a ( 8 b + 7) = u 2 + v 2 + w 2 Every perfect square is congruent 0 or 1 modulo 4, so u, v, w must be even, as long as a > 0. Therefore, we can divide by 4 until we get 8 b + 7 = u ′ 2 + v ′ 2 + w ′ 2
