(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)
