Question

TIL 16, 72, 120) = 21 x 31 = 2 x 3 = 6
23, 32 and 51 are the greatest powers of the prime factors 2, 3 and 5 respective
involved in the three numbers.
So,
LCM (6,72,120) = 23 x 32 x 51 = 360
Remark : Notice, 6 x 72 x 120 # HCF (6, 72, 120) LCM (6, 72, 120). So,
product of three numbers is not equal to the product of their HCF and LCM.
