QUESTION:



Find the LCM of 7(v-3) and 21(v-3).



ANSWER:


we have two expressions,7(v-3) and 21(v-3).

7(v-3) = 7 * (v-3)

21(v-3) = 7 * 3 *(v-3)



Here the  least number of factors which are common to both the terms are
7, 3  and (v-3)


So LCM. = 7*3(v-3)
        


       = 21 (v-3)



Hope you found the explanation useful.
