Given that HCF of 306 and 657 is 9, Find their LCM.

HCF (Highest Common Factor) of two numbers is the highest possible number which divides the two numbers exactly without any remainder and the least common multiple (LCM) of two numbers is the smallest number among all common multiples of the two numbers.

Answer: LCM of 306 and 657 is 22338

Let us see how to find the HCF of 306 and 657

Explanation: 

We will use the formula to find the LCM of 306 and 657.

LCM (a, b) = (a × b) / HCF (a, b)

Given two numbers 306 and 657 and their HCF is 9.

To find : LCM(306,657 )

using the formula,

We have

LCM (306, 657) = (306 × 657) / HCF (306, 657)

= 201042 / 9 

= 22338

Thus, LCM of 306 and 657 is 22338
