Which pair of numbers has a greatest common factor that is a prime number 54 and 99 or 80 and 114?
The greatest common factor of 54 and 99 is 9, which is not prime. The greatest common factor of 80 and 114 is 2, which is prime.
Are there any 2 numbers that don't have a common factor?
Since 1, known as the "multiplicative identity", cannot be counted as a factor, there are many pairs of numbers that do not have common factors, such as 2 and 3, 2 and 5, and 3 and 5. There are many pairs of composite (not prime) numbers without common factors, such as 4 and 9. Also, since prime numbers do not have factors, any pair of primes cannot have a common factor, though a pair in which one number is prime may, e.g. 5 and 10.
What pair of numbers is relatively prime 15 and 21 24 and 49 35 and 135 and 45 and 102?
