Answer 2

Answer:

The LCM of both numbers is 22338.

Step-by-step explanation:

The given numbers are 306 and 657.

The factor form of given numbers are

$306=2\times 3\times 3\times 17$

$657=3\times 3\times 73$

It is clear that 3 and 3 are common factors. So, the HCF of both numbers is

$HCF=3\times 3=9$

If a and b are two numbers then

$a\times b=LCM(a,b)\times HCF(a,b)$

$306\times 657=LCM(a,b)\times 9$

$\frac{306\times 657}{9}=LCM(a,b)$

$22338=LCM(a,b)$

Therefore the LCM of both numbers is 22338.
