Answer 1

500 can't be the HCF of those given numbers
Because 1200 is the multiple of 600 , 400 as well of 200 also..... but 1200 isn't the multiple of 500 so your correct answer is option B

Answer 2

HELLO !!.!..

GOOD MORNING :)

____________________________


It is given that the LCM of two numbers is 1200.

We know that the HCF of two numbers is always the factor of LCM

Checking all the options:

(a) 600 is the factor of 1200.

So this can be the HCF.

(b) 500 is not the factor of 1200.

So this cannot be the HCF.

(c) 400 is the factor of 1200.

So this can be the HCF.

(d) 200 is the factor of 1200.

So this can be the HCF.

● Hence the correct choice is (b).
