Examples of coprime numbers
WebAny pair of prime numbers is always coprime. Example. 5 and 7 are prime and coprime both. Any two successive integers are coprime because gcd =1 for them. Example. 6 … WebFor example, the integers 4, 5, 6 are (setwise) coprime (because the only positive integer dividing all of them is 1), but they are not pairwise coprime (because gcd(4, 6) = 2). The concept of pairwise coprimality is important as a hypothesis in many results in number theory, such as the Chinese remainder theorem .

WebA composite number is a positive integer that can be formed by multiplying two smaller positive integers. Equivalently, it is a positive integer that has at least one divisor other than 1 and itself. Every positive integer is composite, prime, or the unit 1, so the composite numbers are exactly the numbers that are not prime and not a unit. For example, the … Webskip to main content ...
Suppose x and y are two positive integers such that they are called co prime numbers if and only if they have 1 as their only common factor and thus HCF(x, y) = 1.
