Question

Four numbers are in the ratio of
10 : 12:15:18. If their HCF is 3,
find their LCM​

Answer 1

Answer:

Let numbers be 10N, 12N, 15N and 18N.

Let numbers be 10N, 12N, 15N and 18N.Then, LCM = 180N and HCF = N

Let numbers be 10N, 12N, 15N and 18N.Then, LCM = 180N and HCF = NHence, required LCM = 180 x 3 = 540

Answer 2

540 lcm.of rario of no is 10,12,15,18 is 180

So. The lcm of ratio number is

180× hcf= 180×3= 540
