- Radical of an integer
mathematics, the radical of a positive integer"n" is defined as the product of the prime numbers dividing "n":
The radical of any integer "n" is the largest square-free divisor of "n".
The function is multiplicative.
One of the most striking applications of the notion of radical occurs in the
abc conjecture, which states that, for any "ε" > 0, there exists a finite "Kε" such that, for all triples of coprimepositive integers "a", "b", and "c" satisfying "a" + "b" = "c",
