Answer:

I can solve your problems can you understand

Answer 2

Answer:

First find  prime factorization of 396, 1080

Step-by-step explanation:

prime factorization of 396

396 = 2 x 2 x 3 x 3 x 11

prime factorization of 1080

1080 = 2 x 2 x 2 x 3 x 3 x 3 x 5

then find HCF and LCM

HCF =  2 x 2 x 3 x 3 = 36

LCM = 36 x 11 x 2 x 3 x 5 = 11880

product of two no 396 x 1080 = 42780

product of HCF x LCM = 36 x 11880 = 42780

Hence prove, product of two no = product of HCF x LCM
