What are prime number twins?

Are 11 and 13 twin primes?

The numbers 11 and 13 are prime twins. Prime twins are consecutive prime numbers that differ by a difference of two. For example, 3 and 5, 7 and 9 are twin primes.

Are there any more consecutive prime numbers?

The only prime numbers with a difference of 1 are the numbers 2 and 3. More consecutive numbers are not possible, since one of the two would have to be even - and an even number is divisible by 2, and therefore not a prime number (2, of course, is a prime number, but larger even numbers are not).The most you can expect with larger prime numbers is a difference of 2. Very large such "prime twins" are known; a few are 3 and 5; 101 and 103, but much larger ones are known, as well. It is not yet known whether there are an infinite number of twin primes.The only prime numbers with a difference of 1 are the numbers 2 and 3.

What is a prime number times a prime number?

A prime number times a prime number is a composite number. Since prime numbers, except for 2, are odd numbers, a prime number times a prime number is usually an odd number. It will only be an even number if one of the prime numbers is 2. A prime number times a prime number will be a number with four factors unless both prime numbers are the same, in which case it will be a square number with only three factors.
