Answer 1

( c) is the right answer

Answer 2

Given:

The LCM of the two numbers is 52272.

To Find:

HCF of two numbers can be.

Solution:

As given,

The LCM of the two numbers is 52272.

we know that,

The HCF is always a factor of the LCM, so, the HCF of two numbers need to be a factor of  52272.

Now,

52272 can be written as,

52272 = 2 × 2 × 3 × 11 × 396

as we can clearly see that 22, 33, and 44 are factors of  52272. and 28 is not a factor of  52272.

So, 28 can not be the HCF of Two Numbers.

Hence, the 28 can not be HCF.
