One of them.
120 = 2 * 2 * 2 * 3 * 5
240
2 x 2 x 2 x 3 x 5 = 120
120=8x3x5, but 8 is not a prime. We write 8 as 23 .Now the prime factorization is 23 x3x5. We stop because all the factors are primes raised to an exponent power..

Euclid proved there are infinite. He said that if there were a finite number of primes, if you multiply all the primes together and then add 1, the result will be a prime. Thus, there are infinite primes.
Infinity.
The prime factorization of 120 is not 2345 because 2345 is not a factor of 120. The prime factorization of 120 is 2^3 * 3 * 5, which means that 120 can be expressed as the product of primes 2, 3, and 5.
All pairs of two primes are coprime. There are fifteen primes under 50. So that means there are 105 unique pairs of "coprime primes", or more generally, pairs of primes, under 50.
There are an infinite amount of non primes (and primes). It would be impossible to list them.
it is a brute force way to find all the primes in a given range. Remove all the composites, and you are left with the primes
