Not all numbers between 20 and 28 are composite numbers. 23 is a prime number.
Numbers that are prime can't be multiples of 10. Multiples of 10 can't be odd.
Since 256 is an EVEN number, then it is a Composite number. It is definitely NOT a prime number. NB Remember ALL even numbers are composites, because they can all be divided by '2'. . This makes '2' a factor of all EVEN numbers. Remember ALL even numbers end in 0,2,4,6,8. So any number that ends in one of these numbers is a composite , and NOT a prime number. Except for '2' itself, all PRIME Numbers are ODD numbers. However, not all odd numbers are prime numbers., Numbers ending in '5' are odd numbers, but they are NOT prime number because they will all divide by '5' . All odd numbers end in 1,3,5,7,9. However, all prime numbers will only end in either 1,3,7, or 9. Here are the prime number up to '20'. 2,3,5,7,11,13,17,19
