ANSWER

Using the factor tree for the prime factorization of 144,180 and 192, we have

144=24×32,180=22×32×5 and 192=26×3

To find the HCF, we list the common prime factor and their smallest exponents in 144,180 and 192 as follows:

Common prime factor                            Least exponents

                2                                                         2

                3                                                         1                    

∴ HCF=22×31=12

To find the LCM, we list all prime factors of 144,180,192 and their greatest exponents as follows:

Prime factors of 144,180 and 192           Greatest exponents     

                               2                                                           6

                               3                                                           2

                               5                                                           1   

∴ LCM=26×32×51=64×9×5=2880
