A prime number is a natural number greater than 1 that has no positive integer divisors other than 1 and itself. For example, 5 is a prime number because it has no positive divisors other than 1 and 5. In contrast to prime numbers, a composite number is a positive integer greater than 1 that has more than positive divisors. For example, 4 is a composite because it has three positive …

A prime number (or a prime) is a natural number greater than 1 that is not a product of two smaller natural numbers. A natural number greater than 1 that is not prime is called a composite number. For example, 5 is prime because the only ways of writing it as a product, 1 × 5 or 5 × 1, involve 5 itself. However, 4 is composite because it is a …

Is 2 prime? | Brilliant Math & Science Wiki
The statement is ( color{green}{textbf{true}}.) (But it is not at all based on being too small. See Graham’s number.) Proof: The definition of a prime number is a positive integer that has exactly two distinct divisors. Since the divisors of 2 are 1 and 2, there are exactly two distinct divisors, so 2 is prime.

So a number is prime if it is a natural number– and a natural number, once again, just as an example, these are like the numbers 1, 2, 3, so essentially the counting numbers starting at 1, or you could say the positive integers. It is a natural number divisible by exactly two numbers, or two other natural .

Prime Number — from Wolfram MathWorld
A prime number (or prime integer, often simply called a prime for short) is a positive integer p>1 that has no positive integer divisors other than 1 and p itself. More concisely, a prime number p is a positive integer having exactly one positive divisor other than 1, meaning it is a number that cannot be factored. For example, the only divisors of 13 are 1 and 13, making 13 a …

Prime and Composite Numbers – Math is Fun
And the Composite Numbers are made up of Prime Numbers multiplied together. Here we see it in action: 2 is Prime, 3 is Prime, 4 is Composite (=2×2), 5 is Prime, and so on… Example: 12 is made by multiplying the prime numbers 2, 2 and 3 together. 12 = 2 × 2 × 3. The number 2 was repeated, which is OK.
