Question

please please check if this is right and if it is then give me its explanation and if it is wrong then also give me its explanation

Answer 1

I think the answer is 324 because its given that the GCD of 108 and the other number is 54. so, both the numbers should be divisible by 54. In the option given , only 324 is completely divisible by 54. So, the answer according to me should be 324.
