A composite number.
The number 1.
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.
No. One, a counting number, doesn't belong to either of those sets.
Your options C and D are the same, but it is true that 51 is a composite number.
One (1) is not a composite number.
I don't think there is such a thing.
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.
A counting number is the numbers you lear as a little kid, counting numbers are one and up. Integers include the counting numbers, 0, and the opposite (negative) of counting numbers. So yes, a counting number or the opposite of a counting number is an integer.
Squares (or cubes or more) of prime numbers have one distinct prime factor, but if you're counting them individually, all composite numbers have at least two prime factors.
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.
Composite numbers in the world are positive integer numbers that are divisible by at least one positive divisor other than itself and the number one. A composite number cannot be a prime number. The first 10 composite numbers are 4, 6, 8, 9, 10, 12, 14, 15, 16, and 18.
It isn't prime or composite.
4 is the least one digit composite number
1 is neither a prime nor a composite number because it has only one factor (itself (1)). The definition of a prime number is a number that has the factor of one and itself, so one is not prime. The definition of a composite number is a number that has more than 2 factors, so one is not composite. One is a special number.
A composite number is a number that can be divided by one and itself, and more numbers ! Aprime number is a number that can only be divided by one and itself !
21 is composite number because it has more than one number that goes into it
A composite number is basically one that is NOT a prime - a composite number is a product of two or more primes.
Two numbers are consecutive if the second one is the one after the first. Mathematically, if the first number is n then the second is n+1.
Composite A prime number is a number that has only two factors (itself and one) A composite number is a number that has more than two factors.
A number which is divisible by only itself and one is called a prime number. 2145 is not a prime number because it is divisible by 5. Remark: Any counting number ending with number 5(except 5 itself) is a composite number.
It is a composite number because it has at least one positive factor other than one or itself.
747 is a composite number because it has at least one positive factor other than one or itself.
