2 (1,5,6,9)
</span><span>divide the terms by 3 and leave those which are not divisible </span> <span>2 x 3 (1,5,2,3) </span> <span>divide the terms by 3 again and leave those which are not divisible </span> 2 x <span>3 x 3 (1,5,2,1) </span> <span>divide the terms by two and leave those which are not divisible </span>
2 x <span>3 x 3 x 2 (1,5,1,1) </span> <span>divide the terms by five and leave those which are not divisible </span> 2 x <span>3 x 3 x 2 x 5 (1,1,1,1) </span>So the L.C.M is :
2 x <span>3 x 3 x 2 x 5=180 </span>so correct option is D hope it helps
