no it isn't because 4x2 =8.
Yes, they are relatively prime.
No.
no
Yes.
27 is not a prime number and i dont know about 117 but i dont think its a composite # * * * * * The person who gave the above answer has no understanding of "relative primes". Or primes, for that matter. Neither 8 nor 9 is a prime BUT 8 and 9 are relatively prime (or co-prime) because they have no factor in common. That is what relatively prime means. 117 is not a prime, even if the previous answerer thinks otherwise. 27 and 117 are not relatively prime because both are divisible by 3.
No neither of them are because 3x3=9 so it is not prime. 8 is not either because 2x4=8
No, 64 and 144 are not relatively prime. To be relatively prime, the only common factor they could have would be 1. They have other common factors such as 2, 4, 8 and 16.
A number cannot be "relatively prime" except in relation to another number. For example, 8 and 15 are relatively primebecause they contain no prime factors in common.
No they are not.Two numbers are relatively prime if their greatest common factor is 1.For example, 8 and 15 are relatively prime.
No, they are not relatively prime.
It can be. 34 is relatively prime to 35. 34 is not relatively prime to 40.
It can be. 26 is relatively prime to 27. 26 is not relatively prime to 34.
