Penjelasan dengan langkah-langkah:
12!
= 12×11×10×9×8×7×6×5×4×3×2×1
= 95.040 × 42×5×4×3×2×1
= 95.040×210×4×3×2×1
= 95.040×840×3×2×1
= 95.040×2520×2×1
= 95.040×5040×1
= 95.040×5040
= 479.001.600
(2³)!
= 8!
= 8×7×6×5×4×3×2×1
= 56×6×5×4×3×2×1
= 336×5×4×3×2×1
= 1.680×4×3×2×1
= 6.720×3×2×1
= 20.160×2×1
= 40.320×1
= 40.320
