题目：
Write a function that calculates the least common multiple of its arguments; each argument is assumed to be a non-negative integer.
代码：
def lcm2(a,b):
m = max(a,b)
n = min(a,b)
if n == 0:
return 0 while(n>1):
if m%n == 0:
return a*b/n
else:
t = n
n = m%n
m = t return a*b/n def lcm(*args):
lenA = len(args)
if lenA == 1:
return args[0]
elif lenA == 2:
return lcm2(args[0],args[1])
else:
ans = lcm2(args[0],args[1])
for i in range(2,lenA):
ans = lcm2(ans,args[i])
return ans
