All the numbers must have powers of 2 equal to at least 1, with at least one of them having powers of 2 equal to exactly 1 and at least one of them having powers of 2 equal to exactly 3. Break this, and either the HCF or the LCM values will not be met.

Similar argument for powers of 3 and 11.

The rest is all trial and error.
