Question

if two positive integers p and q can be expressed as p =ab2 and q =a3b where a and b are prime number then find hcf and lcm of p and q​

Answer 1

Answer:

let a=2 and b=3 then p= 2*23=12,,q=3*32=18. ... now lcm of 12 and 18 is 36 and hcf of 18,12is 6 so hence it is the values of lcm and hcf of p and q

Answer 2

Answer:

option c) is correct

Step-by-step explanation:

given that, p=ab^2

                    =a*b*b

                  q=a^3b

                     =a*b*b*b

      hence the LCM(P,Q)=a*a*a*b*b

                                        =a^3b^2
