WebThe idea is that suppose n is a positive integer n=pq, where p and q are prime numbers. Assume p greater than square root of n and greater than square root of n. Multiplying these inequalities we have p*q > sqrt n * sqrt n, which implies pq > n. This is a contradiction to our hypothesis n=pq.
WebSince no prime number divides 1, p cannot be in the list. This means that at least one more prime number exists beyond those in the list. ... Since each natural number (> 1) has at least one prime factor, and two successive numbers n and (n + 1) have no factor in common, the product n(n + 1) has more different prime factors than the number n ...
