Question

The HCF of 117 and 221 is 13. Find their LCM.

Answer 1

Step-by-step explanation:

HCF(117,221)=13

Now, we will find the LCM for the given numbers from the factors.

Least Common Multiple is a multiple which is divisible by all the numbers.

Thus, we get

LCM(117,221)=32×131×17

Applying the exponent on terms, we get

⇒LCM(117,221)=9×13×17

Multiplying the terms, we get

⇒LCM(117,221)=1989

Therefore, the HCF of 117 and 221 is 13 and the LCM of 117 and 221 is 1989.
