How many of the following numbers are divisible by 132 ?
264, 396, 462, 792, 968, 2178, 5184, 6336
4
5
6
7
Answer: Option
Explanation:

132 = 4 x 3 x 11

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.

=132/4=33.

=132/3=44.

@Yuvaraj.

I don't think the given solution I applicable for every number.

Eg: 9988 is divisible by all the factors of 88 (4 x 2 x 11).

But then too it is not divisible by 88.

@Koala,

I guess you missed out on the fact that we in here are talking about co-primes while 4 and 2 don't happen to be co-prime factors. 88 = 8 * 11.

And 9988 is not divisible by 8.

This is the wrong answer. In this logic, 462 can also divide by 4, 3, 11.
