Question

three numbers are in the ratio of 3:4:5 and their LCM is 2400 their HCF is

Answer 1

Let the numbers be 3x, 4x and 5x.

Then, their L.C.M. = 60x.

So, 60x = 2400 or x = 40.

The numbers are (3 x 40), (4 x 40) and (5 x 40).

Hence, required H.C.F. = 40.

Answer 2

Step-by-step explanation:

Let the number be 3x,4x and 5x .

then LCM = 60x.

60x=2400

x=2400/60

the number are(3×40)( 4×40) and (5×40)

HCF =40
