WebThe prime number theorem is an asymptotic result. It gives an ineffective bound on π(x) as a direct consequence of the definition of the limit: for all ε > 0, there is an S such that for all x > S , However, better bounds on π(x) are known, for instance Pierre Dusart 's. WebThe only common factor is 1, so they are coprime. On the other hand, 10 and 5: 10 = 5*2 The common factors are 5 and 1, so they are not coprime. Prime numbersare always coprimeto each other. Any two consecutive integers are always coprime. Sum of any two coprimenumbers is always coprimeto their product. 1 is trivially coprimewith all numbers.

"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, Donald Knuth, and Oren Patashnik proposed an alternative notation to indicate that a and b are relatively prime and that the term "prime" be used instead of coprime (as in a is prime to b).
