3/5 ,3

5/5 ,1

/ 1,1

LCM: 270

Answer 2

Answer:

270

Step-by-step explanation:

We will use the formula of LCM (a, b):

LCM (a, b) = (a × b) / HCF (a, b)

HCF (a, b) is the highest common factor of a and b.

Use this formula to find the LCM of 45 and 54.

LCM (45, 54) = (45 × 54) / HCF (45, 54)

= (45 × 54) / 9

= 5 × 54

= 270

So, LCM (45, 54) = 270
