Question

If the HCF of 306 and 657 is 9, then the LCM of 306 and 657 will be .

• A. 22338
• B. 22348
• C. 657

Answer 1

The correct option is A 22338

We know that

$\text{HCF (a,b)}\times \text{LCM (a, b)}=a\times b.$

i.e., $9\times LCM=306\times 657$

$\Rightarrow LCM=\frac{306\times 657}{9}$
$=\frac{201042}{9}$
$=22338$
$\therefore$ LCM of 306 and 657 is 22338.
