[PD] lowest common multiple of lots of periods

[punchik punchik]

hi,  i need to calculate the lowest common mulitple of
50 periods ... 
i have a patch with 50 syncronic grain generators with
a time lag between each other...  and i need to
calculate when the whole  cycle begins again when i
change parameters dinamically.
how can i calculate lowest common multiple of a lot of
numbers in pd? do anybody tried this before... i have
no idea, maybe theres other software that can do it
easily, any hint?

bye
