Answer 1

Answer:

200 right

3+4+5 =12

2400/12

200

Answer 2

Answer:

hcf = 4

Step-by-step explanation:

Let us consider the number be 3x,4x and 5x

The L.C.M of the three numbers be =60x

60x = 2400

x = 2400/60

x = 40

Then the number be

3x = 3 × 40 = 120

4x = 4 × 40 = 160

5x = 5 × 40 = 200

∴ The HCF of the three numbers is 4
