All numbers have factors. Some factors are prime numbers. A prime factor is a factor that is a prime number. A common prime factor is a prime factor that appears on the list of factors of two or more given numbers.
No, the product of two prime numbers is unique.
The product of two prime numbers will be composite.
Composite numbers can be written that way.
As a product of its prime factors: 2*3*3*5*5*7 = 3150 or as 2*32*52*7 = 3150
No. By definition, the product has a proper factor - the prime.
Yes. Composite numbers can be written as the product of prime factors.

70 written as a product of prime numbers: 2 x 5 x 7
the prime factorization
A prime number has only one prime factor, and that prime factor is the number itself.
Written as the product of only prime numbers, 60 = 2 x 2 x 3 x 5.
A semiprime or a prime square.
A factor tree of number is (I think) the numbers that multiply together to form a product. They are prime numbers, too.
It is: 2*2*11 = 44
30 cannot be written as the product of 6 prime numbers. 30 has three prime factors: 2 x 3 x 5 = 30
