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, they are not relatively prime.


No, they are not relatively prime.


It can be. 27 is relatively prime to 28.


It can be. 26 is relatively prime to 27. 26 is not relatively prime to 34.


Yes, they are relatively prime.


Yes, they are relatively prime.


14 = 2 × 7 27 = 3³ → hcf(14, 27) = 1 → 14 and 27 are relatively prime.


Yes! Ten and Twenty-seven are relatively prime.


Yes, e.g. 3 and 5 are relatively prime, 27 (33) and 25 (52) are relatively prime...


hcf(10, 21) = 1 ⇒ 10 & 21 relatively prime hcf(12, 54) = 6 ⇒ 12 & 54 not relatively prime hcf(15, 27) = 3 ⇒ 15 & 27 not relatively prime hcf(21, 38) = 1 ⇒ 21 & 38 relatively prime


One number, by itself cannot be relatively prime - or otherwise. Relative primality is a property of two (or more) numbers.


Yes. The factors of 16 are 1,2,4,8,16 and the factors of 27 are 1,3,9,27 making 1 their only common factor. This makes them relatively prime.



No, they are not relatively prime. They both have 3 as a common factor. 15 = 5 x 3 27 = 3 x 3 x 3


It can't be reduced... they are relatively prime


No - both are divisible by 9.


No. For example: 9 and 27 are both odd but not relatively prime (they both have the factor 3).


They are relatively prime, so the gcf is 1


No because they are both composite numbers


117 is not a prime number. It is divisible by 3. 3*39=117.


20/27 is in simplest form because they are relatively prime.


The factors of 35 are 1, 5, 7, and 35. The factors of 27 are 1, 3, 9, and 27. The only factor they have in common is 1; therefore, 35 and 27 are relatively prime. Alternatively, you can look at the prime factors. The prime factors of 35 are 5 and 7. The prime factors of 27 are 3, 3, and 3. They have no prime factors in common, so they are relatively prime, which means their only common factor is 1.


90 is composite, 117 is prime.


27 factors to [3 3 3] 117 factors to [3 3 13] common factors are [3 3] = 9■


You find their factors and compare them to see which ones are in common. The factors of 27 are 1, 3, 9 and 27. The factors of 77 are 1, 7, 11 and 77. The only common factor they have is 1. Therefore they are relatively prime.
