Answer & Solution
Correct Answer:
Option
B
LCM of (12, 15, 18, 27)
⇒ 4 × 3 × 5 × 3 × 3 = 540
largest 4-digits number = 9999 on dividing by 540 to number = $$\frac{{9999}}{{540}}$$
remainder = 279
Required number = 9999 - 279 = 9720
⇒ 4 × 3 × 5 × 3 × 3 = 540
largest 4-digits number = 9999 on dividing by 540 to number = $$\frac{{9999}}{{540}}$$
remainder = 279
Required number = 9999 - 279 = 9720
