Question

three numbers are in the ratio of 3:4:5 and there LCM is 240 their HCF is​

Answer 1

Answer:

Step-by-step explanation:

3:4:5 = 240(L.C.M)

Let they number be 3x, 4x, 5x=

= > 3x X 4x X 5x = 240

60x = 240

x=24060=4

3 X 4 = 12; 4 X 4 = 16; 5 X 4 = 20

1st =3*4=12

2nd =4*4=16

3rd =5*4=20

so

HCF=4
