A case could be made for all of them.
45 is the only multiple of 5.

An infinite number of integers can be divided by 126.
The LCM of 21 and 18 is 126.
Can't be done with 2 consecutive since one must be odd and one even, but with 3 numbers it's easy: 126/3 = 42 so numbers are 41, 42 & 43. It can even be done with 7 numbers: 126/7 = 18 so numbers are 15, 16, 17, 18, 19, 20 & 21. It's even possible with 9 numbers...
18 is an even number. not an odd one
126 -- 32 -- 81 -- 24 -- 18 -- 45 -- 69 32 is the only member of this group that is not divisible by 3.
126. There is just one number
Yes because if you divide 126 by 18 and get a whole number it is a multiple which 126 divided by 18 is 7.
It is not odd because it is an even number
You might answer this in a couple of different ways. 11 is the "odd" one, as it is the only "odd" number, while 4, 12 and 18 are all "even".
18 is an even number.
126
Even numbers are divisible by 2. 18/2=9, therefore it is an even number.
