In particular, we find PWN with up to 16 distinct prime factors (Table 3, Table 4). The largest PWN we have found has 16 distinct prime factors and 14712 digits. As far as we know, this is the largest PWN known, the previous one being 5328 digits long [14]. Another strange ...

What is the difference between finding the prime factors of a number, and finding that number's prime factorization? Finding the prime factors of a number starts with the division of the number by various primes, until you've found all of the primes that divide into that number; the result...

We need to show that every integer greater than 1 is a product of primes. By induction: assume it is true for all numbers between 1 andn. Ifnis prime, there is nothing more to prove (a prime is a trivial product of primes, a "product" with only one factor). Otherwise, there are...
