64 is an even number. Any number divisible by 2 is even.
64 is an even number since it is divisible by 2 (64 = 2x32).
The sum of the first 8 odd numbers is 64.
64 because 8*8=64. you just have to find the square number.
64 is a multiple of 16, and 81 is a multiple of 27, so I'd say that 36 is the odd one out.

27 and 81 are the odd numbers. Since odd numbers are 1, 3, 5, 7 and 9, look at the last number and you will be able to tell if it's odd or even.
The only number in that list which is not a square number is 27. 27 is a cube number.
