No.
Yes. Their only common factor is 1.
26 and 99 is the only pair which is relatively prime.
117 is not a prime number. It is divisible by 3. 3*39=117.
No because they are both composite numbers that have more than two factors.
No, they are not relatively prime.
No, they are not relatively prime.
No, they are not.
Yes, they are relatively prime.
Yes, 143 and 63 are relatively prime because they have no prime factors in common.
ya they are relatively prime
No, they are not.
No.
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.
Yes, they are relatively prime.
Yes.
Yes.
