Please note that the content of this book primarily consists of articles available from Wikipedia or other free sources online. n mathematics, the radical of a positive integer n is defined as the product of the prime numbers dividing n: displaystylembox{rad}(n)=prod_{scriptstyle pmid natop p~rm prime}p., For example, 504=2^3cdot3^2cdot7 and therefore mbox{rad}(504)=2cdot3cdot7=42., The radical of any integer n is the largest square-free divisor of n, and so also described as the square-free kernel of n. Radical numbers for the first few positive integers are 1, 2, 3, 2, 5, 6, 7, 2, 3, 10, ......

One of the most striking applications of the notion of radical occurs in the abc conjecture, which states that, for any 0, there exists a finite K such that, for all triples of coprime positive integers a, b, and c satisfying a + b = c, c
