first time they toll together at 0th second
lcm of 2,4,6,8,10,12 is 120
means they toll together for each 120 seconds there after;
30 minutes=30*60=1800 seconds
1800/120=15
i.e 15 such intervals are possible
adding the 0th sec, total 16 times they toll together in 30 min

1min=60sec's
30mins=30*60=1800 sec's
the lcm of 2,4,6,8,10,12=120
1800/120=15

=15+1=16 times they toll together in 30 mins
