When two numbers are coprime, it means they do not share common factors other than 1, making them suitable for certain mathematical operations and calculations. Here are a few more examples of coprime pairs:Ĭoprime numbers are important in number theory and various mathematical applications, including cryptography and modular arithmetic. Therefore, 15 and 28 are coprime numbers because their GCD is 1. The only positive integer that both 15 and 28 have in common as a divisor is 1. The divisors of 15 are 1, 3, 5, and 15.In other words, their greatest common divisor (GCD) is equal to 1.įor example, consider the numbers 15 and 28: NCERT Solutions Class 10 Social ScienceĬoprime numbers, also known as relatively prime or mutually prime numbers, are two integers that share no common positive integer divisors other than 1.
