Correct Answer: 1440


Solution : The least number divisible by 6, 18, 20 and 32 is their least common multiple (LCM).
Factors of 6 = 2 × 3
Factors of 18 = 2 × 3 × 3
Factors of 20 = 2 × 2 × 5
Factors of 32 = 2 × 2 × 2 × 2 × 2
$\therefore$ The LCM of 6, 18, 20, and 32 = 2 × 2 × 2 × 2 × 2 × 3 × 3 × 5 = 1440
Hence, the correct answer is 1440.
