Question

2. The LCM of two numbers is 1200. Which of the following cannot be their HCFT
(a) 600
H500
(d) 200​

Answer 1

Given, The LCM of two number= 1200

We clearly know that 600, 400, 200 are factors of 1200 and 500 is not a factors of 1200.

Therefore,

From the available option given, 500 cannot be HCF of since it cannot divide 1200.

( Since HCF is always factors of LCM )
