Tīmeklis2014. gada 22. sept. · gcd ( a, b) = 10, gcd ( b, r) = 10. So it seems that not only do ( a, b) and ( b, r) share the same greatest common divisor, they share all common divisors. If we can prove that the set of common divisors of ( a, b) and the set of common divisors of ( b, r) are the same, simply choosing the greatest value in the set will get us the gcd.

TīmeklisTo prove that it is equivalent relation we need to prove that R is reflexive, symmetric and transitive. (i) Reflexive: Let a ϵ A then ∣ a − a ∣ = 0 is an even number ∴ (a, a) ϵ R, ∀ a ϵ A ∴ R is reflexive (ii) Symmetric Let a, b ϵ A ∀ (a, b) ϵ R ⇒ ∣ a − b ∣ is even ⇒ ∣ − (b − a) ∣ is even ⇒ ∣ b − a ∣ ...
