Question

6. The hcf of two numbers is 11 and their lcm is 7700. If one of these numbers is 275, then the other one is:

Answer 1

Let the numbers be 'a' and 'b'

given that,

HCF(a,b) = 11

LCM(a,b) = 7700

a = 275

b = ?

___________________

By the formula,

a × b = HCF × LCM

275 × b = 11 × 7700

275 × b = 84700

b = 84700 ÷ 275

b = 308

So, the other number is 308
