Question

The HCF of number 14 and 21 is 7. Find their LCM

Answer 1

To Find:-

• LCM of the 14 and 21

Given:-

• HCF of 14 and 21 = 7

Formulae Applied:-

• HCF × LCM = Product of 2 Numbers

Solution:-

• Let LCM be x

Numbers = 14,21

HCF = 7

LCM = ?

HCF × LCM = Product of 2 Numbers

7 × x = 294

7x = 294

x = 294/7

x = 42

So,LCM = 42

Therefore,

LCM of 14 and 21 is 42.

Verification:-

• HCF × LCM = Product of 2 Numbers

7 × 42 = 14 × 21

294 = 294

LHS = RHS

Hence,

It is verified.
