Question

use Euclid division algorithm find whether 231 and 396 are co prime

Answer 1

Hello friend

Here's your answer

If two numbers are co primes then there will be only one common factor i.e 1

So they will be having 1 as their hcf

396=231×1+165
231=165×1+66
165=66×2+33
66=33×2+0
Since their hcf is 33, they are not co primes

Hope it helps!

Answer 2

we have to find out there HCF

231=3x7x11

396=2x2x3x3x11

HCF = 3x11

= 33

if 231and 396 are co-prime number there should be only one factor i.e. 1.

so, it is not an Co prime no.
