Question

if p is prime then find HCF and LCM of p and (p+1)

Answer 1

HCF is 1 and LCM is p(p+1)....hope dis helps u

Answer 2

aNSWER :
   LCM will be product of p and p+1 = p(p+1)
   HCF will be  1.
explanation :
       let the p = 2 , therefore p+1 = 2+1 = 3
 Now , lcm of 2 and 3 = 2*3 =p*(p+1)  (because p=2 and p+1 =3)
   HCF of 2 and 3 is 1 .
HCF is the highest common factor hence 2 and 3 have 1 as the highest common factor .hence 1 is the hcf of 2 and 3.

Hope this helps you !!
Thank You.
