Yes, they are.
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.
12 and 35 are mutually prime as they have no common factors other than 1.
They are co-prime.
Numbers called relatively prime or mutually prime have no common factors or divisors other than 1. Numbers having any common factors or divisors greater than 1 are not relatively or mutually prime.
27 is not prime
To know what numbers are prime between 25-50, you'd have to figure out if any number besides 1 and that number itself can go into that number. Another key, is that all even numbers between 25 and 50 are NOT prime numbers. The only even number, that is prime is 2. So you'd have to go through all the odds between 25-50. For example: 27 is divisible by: 1,3,9, and 27 ~composite~ 29 is divisible by 1 and 29 ~prime~ Hope that helps!
77 is not a prime number. 36 is not a prime number. 77 and 36 are mutually prime as the only common factor they have is 1.
83, 53 and 67 are prime, the rest are composite.
If by 27 over 50 , you mean 27 divided by 50 , or 27/50 , or 27 upon 50 , then 27 over 50 = 27/50 = 27 *2/50 *2 = 54 / 100 = .54
29 is the next prime number after 27. But 27 is not a prime! 3 x 9 = 27!
No, 27 is not a prime number. 3x9 = 27
It can be. 27 is relatively prime to 28.
