Correct Answer - Option 2 : 12
Given:
The ratio of the number = 15 : 6 : 7
LCM of the number = 2520
Calculation:
Let the number be 15x, 6x and 7x
LCM of 15x, 6x and 7x is 210x
210x = 2520
⇒ x = 2520/210 = 12
⇒ x = 12
HCF of 15x, 6x and 7x is x
So HCF of the numbers is 12
∴ The HCF of the numbers is 12.
