Find the LCM and HCF of the following pairs of integers and verify that LCM × HCF = product of the two numbers. (iii) 336 and 54
(iii)
So, 336 = 24 × 3 × 7
and 54 = 2 × 33
∴ H.C.F. = 2 × 3 = 6
L.C.M. = 24 × 33 × 7 = 3024
= 23460
Verification :
L.C.M. × H.C.F. = 3024 × 6 = 18144
Product of the two nos. = 336 × 54 = 18144
L.C.M. × H.C.F. = Product of the two nos.
Verified.
