39
None of those numbers are composite because:in math there are composite and prime numbers.prime numbers can't be factored (have two numbers that multiply to get that number).prime numbers can only be "made" by multiplying themselves by 1.exp. only 1 x 11 gives you 11.composite numbers have factors other than themselves and 1.exp. you can get 24 by multiplying 12 x2, 8x3, 4x6, 24x1.3, 5, 7, and 11 are prime numbers.
27 is composite as it is divisible by 1, 3, 9 and 27
The set of composite numbers includes all whole numbers greater than 1 that are not prime numbers. The first few composite numbers are 2, 4, 6, 8, 11, 13, etc.
Their sum is 37.
