Using tree diagram find the LCM and HCF of the following pairs of integers and verify that LCM× HCF= Product of the two numbers
336 and 54 ​

Answer 1

Prime factorisation of 336=2×2×2×2×3×7

Prime factorisation of 54=2×3×3×3

Hence, LCM of 336,54=2×3×2×2×2×7×3×3=3024

And HCF of 336,54=2×3=6

Now, LCM × HCF =3024×6=18144

Also, 336×54=18144
