In mathematics, two integers a and b are said to be coprime or relatively prime if they have no common positive factor other than 1 or, equivalently, if their greatest common divisor is 1. The notation a bis sometimes used to indicate that a and b are relatively prime. Extracted from Wikipedia.

Is 16 and 18 coprime numbers?
No.
What number coprime with 18?
coprime numbers with 18 are : 17 and 19.
Are 9 and 10 coprime numbers?
9 (factors 1, 3, and 9) and 10 (factors 1, 2, 5, and 10) are coprime numbers. Numbers are coprime (also called relatively prime) if 1 is their only common factor.
How many pairs of coprime primes are there between 1 and 50?
All pairs of two primes are coprime. There are fifteen primes under 50. So that means there are 105 unique pairs of "coprime primes", or more generally, pairs of primes, under 50.
When is the LCM of two numbers equal to the product of the two numbers?
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) = 72
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.
Are 6 and 8 coprime numbers?
No. If two numbers are coprime, they must have no common factors.
Fill in the syllogism. If ab and bc then a?
The answer will depend on whether or not the relationship between the pairs of variables is transitive. In mathematics, not all relationships are transitive.For example, if the relationship is "is coprime with", then2 is coprime with 3, 3 is coprime with 4 but 2 is certainly not coprime with 4.
Are 38 and 57 coprime?
No.
Are 6 and 8 coprime?
No.
Are 11and27 coprime?
Yes they are.
Are 2 and 14 coprime?
No.
Is 5 and 7 coprime?
Coprime numbers are those in which only 1 and that number (say 5) can be divisible by it. Both 5 and 7 would be coprime numbers because they are numbers divisible by only themselves and 1.
