Question

If   a    and    b are two prime numbers then HCF( a,b) and  LCM ( a , b) are (a.) 1,a/b
 (b.) 0, ab
 ( c.) 1, ab
 (d.) ab ,1​

Answer 1

Answer:

option a

explanation -

We know that,

product of two numbers= HCF× LCM

As the numbers are prime numbers so their HCF must be 1

and ab is the LCM
