Yes because 1 is a factor of any Prime number. In fact, 1 is always the gcd (same as gcf) of any two distinct prime numbers.

The GCF of any two prime numbers is 1 and the LCM is their product.
The two numbers are coprime so the gcf is 1.
Yes. For two prime numbers, the LCM is their product: one times the other. Multiply the two. (e.g. LCM of 5 and 7 is 35) By formula, the LCM for x and y is LCM = x * y / GCF and for primes, the GCF (greatest common factor) is 1.
The GCF is 1.
The GCF is 1.
