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.
What does coprime mean?
Two numbers are coprime if they have unity (1) as their only common factor. Example 1: 17 and 19 - any two prime numbers are also coprime. Example 2: 15 and 64 - neither is a prime, but they have no common factor except. The factorizations are 3x5 and 1x15; and 1 x 64 and 26, respectively.
How can you use prime factorization of two numbers to determine whether they are relatively prime?
let's have two numbers a and b and a set of primes (pi) Suppose a = pa pa+1pa+2... and b = pb pb+1 pb+2... If at least one pi in both factorization is in common then the two numbers are not coprime (relatively prime), if none is in common then they are coprime
What are coprimes?
Coprimes, or relative primes, are two or more numbers that share no common divisors. To determine whether numbers are relatively prime, find their greatest common denominaotr. If it's one, they're coprime.
HCF of two coprime number is?
The product of the two numbers
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
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.

Can 8 over 45 be reduced?
No, the two numbers are relatively prime (or coprime).
What will be the HCF of two coprime numbers 15 and 37?
The GCF of any two co-prime numbers is 1.

Are 6 and 8 coprime numbers?
No. If two numbers are coprime, they must have no common factors.
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.
What is the least common multiple of 2 coprime numbers?
The least common multiple of two numbers is the product of those two numbers divided by their greatest common factor. It the two numbers are coprime (or relatively prime), their greatest common factor is 1. Therefore, their least common multiple is a x b ÷ GCF (of a and b) = a x b ÷ 1 = a x b. The least common multiple of two coprime numbers is the numbers multiplied together.
What are coprimes?
Coprimes, or relative primes, are two or more numbers that share no common divisors. To determine whether numbers are relatively prime, find their greatest common denominaotr. If it's one, they're coprime.
