No.
No.
Yes, they are relatively prime.
NO. Because they have 2 as their common factor aside from 1.
no
no it isn't because 4x2 =8.
Yes.
No. They both contain the factor 2. 68 = 2 x 2 x 17 118 = 2 x 59 Their LCM is 4012, not 68 x 118 = 8024
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.
