Question 751207
the so called lcm must be a multiple of both expressions, so it must include the greater factor of each common factor as well as all the factors exclusive to each expression:


{{{ 12x^8w^5u^4=2^2*3*x^8w^5u^4 }}} and {{{ 10x^7w^2=2*5*x^7w^2 }}}


must be

{{{(2)^2*(3)*(5)*(x)^8*(w)^5*(u)^4=60x^8*w^5*u^4}}}
