The Fundamental theorem of arithmetic.
An even number because every prime number gretaer than 2 is odd.
Every positive integer greater than 1 can be expressed as the product of a unique set of prime factors. The count of these factors is the prime factors number for the number.
Because every number is either odd or even. Even numbers are divisible by two, which means that (with the exception of 2 itself) they by definition are not prime.
No. A notable exception is the set of prime numbers.
The same as every other even numbers greater than 2, 124 is a composite number.
