Frequently Asked Questions
What is a prime number?
A prime number is a natural number greater than 1 that has no positive divisors other than 1 and itself. The first few primes are 2, 3, 5, 7, 11, 13.
Is 1 a prime number?
No. By definition, a prime number must have exactly two distinct positive divisors. 1 only has one divisor (itself), so it is not prime.
What is prime factorization?
Prime factorization breaks a number down into the prime numbers that multiply together to make it. For example, 12 = 2 × 2 × 3.
