5 |1,1

   

Answer 2

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

LCM (a, b) = (a × b) / HCF (a, b)

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

Use this formula to find the LCM of 45 and 120

LCM(45, 120) = (45 × 120) / HCF (45, 120)

LCM(45, 120) = 5400/15

LCM(45, 120) = 360

Thus, LCM of 45 and 120 is 360.
