There are more than 25 prime numbers; there are an infinite number of prime numbers.

no. because there are more composite numbers than prime numbers It depends on the place you choose to pick the prime number (e.g. 457 or 7577?). The bigger the number the less likely it is a prime.A formula gives the probability for a number being prime (Prime Number Theorem).

The only number less than 20 that is odd and has 2 different prime factors is 15. The prime factors of 15 are 3 and 5, both of which are prime numbers. Any other odd number less than 20 either has only one prime factor or has more than 2 prime factors.

There are more composite numbers than prime numbers because most numbers have more factors than just 1 and a number itself.

Numbers can be checked to see if they are primes simply by factoring them. Every prime number has exactly two factors, 1 and the number itself. If there are more or less than 2 factors, the number is not a prime. 1 has only one factor so it is not a prime, and composite numbers have 3 or more factors.

Prime numbers have two factors. Composite numbers have more than two. Numbers with less than two are neither.

There is no correct answer to this question, because it is nonsensical.The question asks for a largest prime number. By definition, a prime number is NOT the product of 2 (or more) prime numbers. So it is nonsensical to ask for any prime number that is the product of 2 prime numbers.

A prime number is a number that has exactly two factors: 1 and itself. All whole numbers greater than 1 are either prime numbers or can be written as the product of prime numbers. There are an infinite number of prime numbers, but they occur less frequently among larger numbers. Prime numbers are important in cryptography and number theory.Read more: http://wiki.answers.com/Q/FAQ/7008#ixzz1LVq5EURw

1, 2, 3 ,5 , and 7 are all prime numbers less than 10. The lower the number is, the more likely it is to be prime. There is only one number, 2, that is even.

I see no reason why they would do that. Prime numbers can be used for encryption, but there are algorithms that can quickly generate a more or less random prime number. No need to pay for the "discovery" of a specific number!

A composite number is the product of two or more prime numbers.

Any number squared except 0 is a perfect square so it follows that prime numbers are less common than perfect squares.
