What should replace the question mark?

\[\frac{854 × 854 × 854 - 276 × 276 × 276}{854 × 854 + 854 × 276 + 276 × 276}=?\]

578

\[\frac{854 × 854 × 854 - 276 × 276 × 276}{854 × 854 + 854 × 276 + 276 × 276}=?\]

(854³ - 276³ )/ (854² + 276² + 854*276)

a³-b³ = (a−b)(a² + b² + ab)

Thus the expression becomes: (854-276) = 576

The correct answer is Option (2) → 578
