[seqfan] LCM of sums of digits

[Éric Angelini]

Hello SeqFans,
Jean-Marc Falcoz discovered the 
integer 32760 that has a  nice property.
Make all possible sums of two digits:
3+2=5
3+7=10
3+6=9
3+0=3
2+7=9
2+6=8
2+0=2
7+6=13
7+0=7
6+0=6
The LCM of all those sums is 32760 itself.
Are there more integers like this?
Best,
É.
