Answered by Manjula29

Two numbers are co-prime if their hcf is 1.Let us find the hcf of 231 and 396. applying the Euclid's division lemma:396=231×1+165 231=165×1+66 165=66×2+33 66=33×2+0 the HCF of 231 and 396 is 33. Ans,Thus the numbers 231 and 396 are not co-primes.

Manjula29: Sry, in the place of 546, I wrote 396 by mistakly,,

applying the Euclid's division lemma.546=231×2+84
231=84×2+63.
84=63×1+21
63=21×3+0
The HCF of 546 and 231 is 21,
Ans, thus 546 and 231 ,these no are not co prime,
