If your question was really "Are 3 and 1 mutually prime?" The answer is no as by definition nothing can be mutually prime with 1 (which also by definition is not a Prime number).

The first prime number is 2. The second is 3. The third is 5. The fourth is 7. The fifth is 11. etc.

However numbers can be "mutually prime" even when the numbers themselves are not prime numbers.

For example 12 and 6 are neither mutually prime nor prime numbers, but 15 and 4 are mutually prime but neither is a prime number.
