If an odd number has more than two factors then it is a composite number but if it has only two factors then it is a prime number. Although all prime numbers are odd except for 2 many more odd numbers are composite numbers having more than two factors as for example 21 is an odd number whose factors are 1, 3, 7 and 21.

29 = 512 36 = 729 26*32 = 576

A composite number is a number that has factors other than 1 and itself. Assuming that you are not including the numbers 25 and 35. Prime numbers are numbers whose only factors are itself and one, so if you find the prime factors of each number: 26 factors to 2, 13 27 factors to 3,3,3 28 factors to 2,2,7 29 prime 30 factors to 2, 3, 5 31 prime 32 factors to 2,2,2,2,2 33 factors to 3, 11 34 factors to 2, 17.
