(i)


(ii)


(iii)


(iv)


(v)


(vi)


(vii)


(viii)

(i) - =

= (Therefore, L.C.M of 8 and 8 is 8)


=


(ii) - =


= (Therefore, L.C.M of 9 and 9 is 9)


(iii) - =


= (Therefore, L.C.M of 11 and 11 is 11)


(iv) - =


= (Therefore, L.C.M of 13 and 13 is 13)


(v) - =


= (Therefore, L.C.M of 8 and 4 is 8)


(vi) - =


= (Therefore, L.C.M of 6 and 3 is 6)


=


(vii) - =


= (Therefore, L.C.M of 14 and 7 is 14)


(viii) - =


= (Therefore, L.C.M of 22 and 33 is 66)
