We will take LCM of 4, 6 and 8 because if we join the cuboids of these dimensions and then every dimension of these cuboids will be formed by 4, 6 and 8 but since we have to make a cube and cube has all sides equal therefore sides should be multiple of 4, 6 and 8 all of them

The smallest multiple of 4, 6 and 8 is LCM of them i.e. 24 therefore side of the smallest such cube will be 24
