Question

Three number ratio 1:2:3 and their Hcf 12 and what is L.C.M number

Answer 1

here your answer.....

lcm=72

numbers=[ ratio]× hcf

=(1:2:3)12

the numbers are

12,24,36

lcm is

12 (12,24,36)

(1,2,3)

12×1×2×3=12*6=72

Answer 2

Answer:

Let the three numbers be x, 2x, 3x respectively.

x is the common factor of the prime numbers 1, 2, 3. So, x must be the hcf.

x = 12

LCM = HCF * Numbers

= 12 * 1*2*3

= 72
