A prime number is a number with exactly two distinct factors: itself and oneThe only factors of 3 are 1 and 3 so it is a prime number.The factors of 6 are 1,2,3 and 6 which has more than two factors so it is not a prime number.
All numbers have factors. Some factors are prime numbers. These are known as prime factors. 2 and 3 are prime factors of 6. 1 and 6 are not prime factors of 6.

1,2,3,5,7,11,13,17,19,23,29,31.... A prime number has exactly two factors. 2 is prime (its factors are 1 and 2) 3 is prime (its factors are 1 and 3) 5 is prime (its factors are 1 and 5) 1 is not prime (its only factor is 1, this is 1 factor, not 2) 4 is not prime (it has 3 factors: 1, 2, and 4) 6 is not prime (it has 4 factors: 1, 2, 3, and 6)
A prime number is a number with exactly two distinct factors: itself and oneThe only factors of 3 are 1 and 3 so it is a prime number.The factors of 6 are 1,2,3 and 6 which has more than two factors so it is not a prime number.
Prime numbers have two (and only two) factors. 1 doesn't have enough factors and 6 has too many to be primes.
23 is a prime and so does not have 6 factors.
When two or more numbers have one or more of the same primes as factors, those prime factors are called common prime factors. For example, the prime factors of 6 are 2 and 3, and the prime factors of 21 are 3 and 7, so 3 is a common prime factor of 6 and 21.

If the two prime numbers are different: You get the two prime numbers, plus 1, plus the product. For example, if you multiply 2 x 3 = 6, the factors of 6 are 2, 3, 1, and 6. If the two prime numbers are the same: You get the prime number, 1, and the product. For example 2 x 2 = 4. The factors of 4 are 2, 1, 4.

It is not a prime number. It has factors of 2, 3, 6, and 7.
