Pairwise coprime
http://dictionary.sensagent.com/pairwise%20coprime/en-en/ A set of integers $${\displaystyle S=\{a_{1},a_{2},\dots a_{n}\}}$$ can also be called coprime or setwise coprime if the greatest common divisor of all the elements of the set is 1. For example, the integers 6, 10, 15 are coprime because 1 is the only positive integer that divides all of them. If every pair in a set of … See more In number theory, two integers a and b are coprime, relatively prime or mutually prime if the only positive integer that is a divisor of both of them is 1. Consequently, any prime number that divides a does not divide b, and vice versa. … See more The numbers 1 and −1 are the only integers coprime with every integer, and they are the only integers that are coprime with 0. A number of … See more Given two randomly chosen integers a and b, it is reasonable to ask how likely it is that a and b are coprime. In this determination, it is convenient to use the characterization that a and b are coprime if and only if no prime number divides both of them (see See more In machine design, an even, uniform gear wear is achieved by choosing the tooth counts of the two gears meshing together to be relatively prime. When a 1:1 gear ratio is desired, a gear relatively prime to the two equal-size gears may be inserted between them. See more When the integers a and b are coprime, the standard way of expressing this fact in mathematical notation is to indicate that their greatest common divisor is one, by the formula gcd(a, b) = 1 or (a, b) = 1. In their 1989 textbook Concrete Mathematics, Ronald Graham See more Two ideals A and B in a commutative ring R are called coprime (or comaximal) if $${\displaystyle A+B=R.}$$ This generalizes See more All pairs of positive coprime numbers (m, n) (with m > n) can be arranged in two disjoint complete ternary trees, one tree starting from (2, 1) … See more

WebNov 10, 2008 · The sequence of primes is challengingly irregular. Possibly, sequences of pairwise coprime natural numbers may serve as an approximation, which in some ways is easier to control. Or one may consider the prime divisors of terms of such a sequence to be exceptions, aiming at the properties which hold for all other (unexceptional) primes. WebTwo positive numbers are called coprime (or relatively prime) if their greatest common divisor is 1. A set of integers is said to be pairwise coprime if for every pair of different element (a, b), a and b are co-prime. Given set S of N first positive integers, your task is to find the largest subset S' of S such that S' is pairwise coprime. Input
