4 is the first composite number greater than 1.
The number 1.
A composite number.
No. One, a counting number, doesn't belong to either of those sets.
All natural numbers (counting numbers) greater than one are either prime or composite. If divisible by only one and the number itself, it is prime; if divisible by other natural numbers, then is composite. One is the only natural number that is neither prime nor composite.
I don't think there is such a thing.
One (1) is not a composite number.
Your options C and D are the same, but it is true that 51 is a composite number.
ANSWER: One is not a composite number.One is not also a prime number.
No. The first odd number, counting up from one, that is not a prime number, is 9.
Start looking for factors; you already know that 1 is a factor, and that the number itself is a second factor (unless the number is 1). As soon as you find a factor that is neither 1 nor the number itself, the number is composite. If you find exactly two factors, the number is prime. If the number has only one factor, the number is 1, which is neither prime nor composite.
There is not just one set of numbers to which 6 belongs.. It is an even number and a composite number. It also belongs to each of the following:Natural (N), Counting N0, Integer Z.
Not all numbers are either prime or composite. The number 1/2 is neither prime nor composite. If you are referring only to the natural or counting numbers, note that every natural number is equal to the product of itself and 1 so each number has at least one divisor, itself. If it has no more divisors, then it is prime. If it has more than itself as a divisor, then it is composite.
