Question

Three numbers are in the ratio of 3:4:5 and their LCM is 2400. Then, their HCF is

विकल्प

• 40

• 80

• 120

• 200

Answer 1

40
Explanation:
Let the numbers be 3x, 4x and 5x.
Then, their LCM = 60x
So, 60x = 2400 or x = 40
∴ The numbers are (3 x 40), (4 x 40) and (5 x 40).
Hence, required HCF = 40
