Question

If a and b are prime numbers, find their HCF and LCM.

Answer 1

Answer:

We know " A Prime Number can be divided evenly only by 1 or itself. And it must be a whole number greater than 1. " Or we can say these numbers does't have any common factor.

So

As a, b are two prime numbers, So

a = ax 1

b = bx1

So,

HCF (a and b) = 1 LCM (a and b) = axb

Hope it helps you!

Answer 2

Answer:

The HCF of a and b which are prime numbers is 1.

The LCM of a and b which are prime numbers is ab/ a x b.
