396, 1080
Prime factorization:
{tex}396 = 2 ^ { 2 } \times 3 ^ { 2 } \times 11{/tex}
{tex}1080 = 2 ^ { 3 } \times 3 ^ { 3 } \times 5{/tex}
HCF = product of smallest power of each common prime factor in the numbers {tex}= 2 ^ { 2 } \times 3 ^ { 2 } = 36{/tex}
LCM = product of greatest power of each prime factor involved in the numbers {tex}= 2 ^ { 3 } \times 3 ^ { 3 } \times 5 \times 11 = 11880{/tex}
