Question

Three numbers are in the ratio 3:4:5 and their LCM is 2400 what will be their HCF? ​

Answer 1

Answer:

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

LET THE NOZ BE 3X,4X ,5X

3×4×5×X = 2400

X= 40 ....

THEREFORE NOZ ARE 3×40 =120

4×40=160

5×40 =200

HCF = 2×2×2×5 = 40 ......
