Question

Please answer this Factorisation question with steps

Answer 1

Answer:

HCF is highest common factor.. so first find the factor of each element and then find all common factor which will be the HCF.

a) 12xy  = 2*2*3*x*y       3x = 3*x

3 and x are common so HCF = 3x

b) 54xyz = 2*3*3*3*x*y*z     $12x^2y^2$ = 2*2*3*x*x*y*y

Common 2,3,x,y so HCF = 2*3*x*y = 6xy

compute the HCF of others in similar way.
