1 is not considered to be a prime or composite number because it has only one factor which is itself.
No. 2 is the least prime number and it is the only even prime number.
because it is 1
A prime number is an integer greater than one which has no positive integral factors other than itself and one.A composite number (or non-prime) is an integer greater than one which has positive integral factors other than itself and one. Alternate definition: A composite number (or non-prime) is an integer greater than one which has at least two prime factors.The numbers 0 and 1 are neither prime nor composite, by definition.60 = 1 x 2 x 2 x 3 x 5, so 60 is a composite number.59 and 61 are prime numbers, because the only way to describe them as a product of positive integers is 59 = 1 x 59 and 61 = 1 x 61.3599 is a composite number, because 3599 = 1 x 59 x 61.Prime numbers are numbers that only 1 and the number itself can be divided into (e.g, 3: no other number can divide into it)Composite numbers are numbers that more than 1 number besides itself and 1 can be divided into (e.g, 9: more than 1 number can divide into 9).-------------------------------------------------------------------------------------------A Prime Number is a number that only has 2 factors, 1 and itself.Example:11A Composite Number has more than one factor besides 1 and itself.Example:44Note ALL even numbers (except 2) are composite.
All numbers are divisible by themselves and one, BUT a number divisible ONLY by itself and one is called a prime number.prime numbers can only be divided by themselfs and 1a prime number
