Question

for the given pairs of numbers, show that the product of their HCF and LCM equals their products : 27 and 90

Answer 1

Here is your answer
-----------------------------------
Given numbers are:27,90
There LCM=3x3x3x5x2 =270

There HCF=3x3 =9

so, HCF xLCM = product of two numbers
9 x 270 = 27 x 90
2430 = 2430
Hence proved,

Answer 2

LCM=3x3x3x5x2 =270

There HCF=3x3 =9

We beed to prove that LCM x HCF= 27 x90

9 x 270 = 27 x 90

2430 = 2430

Done.
