Question

Prime factors of a and b are a=x³yz³ and b=xy³z find LCM (a,b) and hcf (a,b)​

Answer 1

Answer:

HCF = xyz ; LCM = $x^{3} y^{3} z^{3}$

Step-by-step explanation:

a = x . x . x . y . z . z . z

b = x . y . y . y . z

common factors are [ x, y, z]

HCF = xyz

LCM = $\frac{(a b)}{HCF(a,b)}$

= $x^{4} y^{4} z^{4\\}$/ xyz

= $x^{3} y^{3} z^{3}$
