Question

if 2 positive integers A and B can be expressed as A=xy3 and B=xiy2z; x,y being prime numbers ,the LCM (A,B) is​

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)=xy
