Question

If a=xy^2 and b-x^3y^5 where x and y are prime numbers then find LCM and HCF of a and b

​

Answer 1

Answer:

HCF by using the prime factorization method.

Step1:

Find the prime factorization of each of the number

Step2:

The product of all common prime factor is the HCF

Here,

⇒a=x×x×y×y

⇒b=x×y×y

common Factors are x×y×y

Thus ,

HCF(a,b)=xy2
