no,31 and 62 coprimes are not coprimes . as ,62 is divisible by 31 .so,their GCD=2

First, find the prime factorization of the number. For instance, with 45: 45 = 3 * 3 * 5 = 32 * 51 Now, from this prime factorization, any numbers whose prime factorizations do not include these factors is coprime to the number you have.

Yes

Coprimes require two integers 50 and 1 are coprimes for example, but 50 and 6 are not because both are evenly divisible by 2. 1 number cannot be a co-prime.

are co-prime

Joint prime numbers, or coprimes, as they are better known, are numbers which do not share any factor in common (other than 1). The numbers may not themselves be prime. Any pair of successive integers must be coprime even if one or both of them may be composite. For example, 15 and 16.

A factor of a number is any number which the original number can divide evenly into (that is, it can divide without leaving a remainder or fraction). Therefore, the factors of 3 are 1 and 3. The factors of 5 are 1 and 5. A common factor is a factor which is present in both lists. In this case, the only common factor of 3 and 5 is 1. Thus the greatest common factor of 3 and 5 is 1.

2 numbers are relatively prime, or coprime, if there is no whole number other than 1 that goes into both numbers.
