Hii friend,
Prime factorisation of 72 = 2 × 2 × 2 × 3 × 3
Prime factorisation of 126 = 2 × 3 × 3 × 7
Prime factorisation of 168 = 2 × 2 × 2 × 3 × 7
HCF of 72 , 126 and 168 = 2 × 3 = 6
LCM of 72 , 126 and 168 = 2 × 3 × 2 × 2 × 3 × 3 × 7 = 1512.
Product of three numbers = 72 × 126 × 168 = 1524096.
Whereas,
Product of HCF and LCM = 1512 × 6 = 9072
Hence,
Product of three numbers is not equal to Product of their LCM and HCF
HOPE IT WILL HELP YOU... :-)
