No.
26 and 99 is the only pair which is relatively prime.
Yes. Their only common factor is 1.
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, 63 and 74 are not relatively prime because they have a common factor of 1.
Yes, 143 and 63 are relatively prime because they have no prime factors in common.
ya they are relatively prime
No.
No, they are not.
Yes, they are relatively prime.
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.
30 and 63 are relatively prime numbers. The factors of 30 are 1, 2, 3, 5, and 30, and the factors of 63 are 1, 7, 9, and 63. Two or more numbers are relatively prime if 1 is their only common factor.
Yes.
No - both are divisible by 9.
