A Prime number has only 2 factors which are 1 and itself. Composite numbers are everything else except 1 and 0. 1 and 0 are neither prime, nor composite. 256 is composite.
Prime factors of 256=2x2x2x2x2x2x2x2 (or 28)
256 = 28
256 is composite because it ends in an even number so the number 2 goes in it.
28 = 56
no it can be dvided by 2,128,4,64,8,32 and 16
Count the number of twos in its prime factorization.
No, 256 is not a composite number. It is a power of 2, specifically 2 to the power of 8 (2^8), and only has 2 factors (1 and 256), making it a prime number.
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
2^8 = 256
256 = 28
28 = 256
256 = 28.
