Using prime factorization method find the HCF and LCM of 72 , 126 and 168. Also show that HCF x LCM is not equal to the product of the three numbers

Text Solution

Verified by Experts

`72=2^3xx3^2`
`126=2xx7xx3^2`
`168=2^3xx7xx3`
H.C.F=`2xx3=6`
L.C.M=`2^3xx3^2xx7=504`
Product of HCF and LCM=3024,product of three numbers=1524096
product of numbers and their hcf and lcm is not equal.
hence shown.
