What is a co-prime number?

There is no such thing as a coprime number.Two integers are said to be relatively prime (or coprime) if they have no common positive factor, other than 1. Examples:Any two different prime numbers are coprime.16 and 27 are coprime.14 and 18 are not coprime. They have the common factor 2.


Could the product of two coprime numbers be a prime number?

No, since it has at least two more factors other than one and itself, it's by definition not prime. Any such number would always be composite.


Two numbers are said to be coprime if they do not have a common factor other than 1 they are?

Another term for co-prime is relatively prime.


Is the 5 and 12 are coprime numbers?

No 5 is a prime number and 12 is composite number


Are 12 and 15 relatively prime?

No, 12 and 15 aren't relatively prime, because they both share as a prime factor 3. Dividing both12 and 15 by 3 gives 4 and 5 respectively. Consecutive numbers are always coprime. Coprime numbers are relatively prime to each other, as they share no prime factors, for example 33 and 35,


Is 31 and 62 coprime?

When is the LCM of two number equal to their product?

When the two numbers are coprime. Coprime numbers need not be prime numbers - they must not have any factor in common (other than 1).So, for eaxmple, neither 8 nor 9 are prime numbers but they are coprime and so,LCM(8 , 9) = 72Read more: When_is_the_LCM_of_two_numbers_equal_to_the_product_of_the_two_numbers

Is one relatively prime with any number?

Can you simplify 17 over 24?

No, since 17 and 24 are coprime integers (17 is a prime number).
