Question

Telephone poles occur at equal distance of $220$ m along a railway track and heaps of stones are put at equal distance of $360$ m along the same track. The first heap is at the foot of the first pole. How far from it along the track is the next heap, which lies at the foot of a pole?

Answer 1

Lets find the LCM of both the numbers

$2$	$220,360$
$2$	$110,180$
$5$	$55,90$
	$11,18$

LCM of $220$and $360$ is $2\times 2\times 5\times 11\times 18=3960$

Hence the next heap, which lies at the foot of a pole will be at a distance of $3960m$
