A number as a product of prime numbers would be "x".
Numbers divisible by 1 & number itself are called prime numbers. These numbers also have the property to be odd numbers.
Prime factorization of 27 = 3x3x3
That's called the prime factorization.
You can't write that as the sum of two prime numbers. Note: Goldbach's Conjecture (for expressing numbers as the sum of two prime numbers) applies to EVEN numbers.
2x2x2x3
2x2x3x5
2x2x3x3x3
fdsgfhgdfhgdf
Since there is an infinite set of prime numbers the answer would be infinity.
2x2x2x2x3x3=144
2x21x11
