How many of the following numbers are divisible by 132 ?
264, 396, 462, 792, 968, 2178, 5184, 6336
264, 396, 462, 792, 968, 2178, 5184, 6336
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.

11, 3, 4 is H.C.F of 132 that's why, we take it.

=132/11=22.
=132/4=33.
=132/3=44.
=132/4=33.
=132/3=44.

I just got confused with the logic, there are many answers to this not one. I agree with dividing each by 132 to get a whole number with no reminder. Its more satisfying.

It's simple and easy.
Total nos = 8,
132/8 = 16.5.
As given, we can do 16 * 8 = 128.
132 - 128 = 4.
Total nos = 8,
132/8 = 16.5.
As given, we can do 16 * 8 = 128.
132 - 128 = 4.

We can't take 2 as it will not sufficient for 132 but if we take 2 then we will be checking for 66.
