So, if the number divisible by all the three number 4, 3 and 11, then the number is divisible by 132 also.

264 → 11,3,4 

396 →  11,3,4 

462  → 11,3 (X)

792  → 11,3,4 

968  → 11,4 (X)

2178  → 11,3 (X)

5184   →3,4 (X)

6336  → 11,3,4 

Therefore the following numbers are divisible by 132: 264, 396, 792 and 6336.


Required number of number = 4.
