Prime numbers are numbers that are only divisible by 1 and the number itself. Some examples of prime numbers are:

1,2,3,5,7,11,13,17,19,23,27,29,31,37,41,etc.

Prime numbers can go on forever; you just have to find out if its only factors are 1 and itself.

Example:

9 is not a Prime number because other than 1 and 9, it is also divisable by 3.

13 is a Prime number because its only factors to equal 13 are 1 and 13.

Even numbers, with the exception of 0 and 2, cannot be prime numbers.

I'm a different person:

1 isn't a prime number although many people think it is. this is because a prime number is divisible by itself and 1 but in this case it is the same number so this time 1 isn't a prime number. The definition is that a prime number is a natural number (integers 1 and greater) that has exactly two unique factors: 1 and itself. The number 1 does not have two unique factors.

A prime number is a number that cannot be generated by multiplying any 2 whole numbers (aside from 1 and itself). For example, 8 is not a prime number because you can get it by multiplying 4X2. 7 on the other hand IS a prime number because there are no whole numbers you can multiply to generate it aside from 1X7.

Three are infinitely many primes and every number can be expressed as the product of primes in exactly one except for the order of the factors.
A prime number is any number that has only 2 distinct (different) factors, namely 1 and itself.

for example:

• 7 is a prime number since the only factors of 7 are 1 and 7
• 6 is not a prime number since it has the factors 1, 2, 3 and 6.

1 is not a prime number since, although it is only divisible by 1 and itself (as itself is 1) it does not have two distinct (different) factors - it has only one factor: 1. The number 1 is called a Unit.

Numbers which are not prime (except for the number one) are called composite numbers, for example 6 is a composite number.

A prime number is a number that can only be divided by itself and 1. A prime number (or a prime) is a natural number greater than 1 that has no positive divisors other than 1 and itself. A natural number greater than 1 that is not a prime number is called a composite number.

Prime numbers are numbers which are only divisible by 1 and itself. For example 2 is a prime number because it is only divisible by 1 and itself (2) But, 6 isn't a prime number because not only is it divisible by 1 and itself (6) it is also divisible by 2 and 3.

Prime numbers are numbers that can only be divided by 1 and their self such as

1 x 7 = 7. Prime numbers are 2, 3, 5, 7, 11, 13, 17, 19, 23, 29, 31, 37, etc

Numbers that can only divide by themselves and one.

They are integers which are greater than 1 and can only be evenly divided by 1 and themselves.

Prime numbers are the numbers that have only 2 factors which are 1 and the number itself.

example: 13

1 x 13

(has only 2 factors: 1 and 13)

2 is the smallest and the only even prime number and 1 is neither a prime number or a composite number.
