(By the way: there's a subtle bug in lcm() that will hit you in Python

Er, ignore this. Division in Python 3 only returns a float if the
remainder is non-zero, and when dividing by the gcd the remainder should
always be zero.
You were right the first time.
IDLE 3.0rc3
>>> a = 4/2
>>> a
2.0
lcm should return an int so should be written a//gcd(a,b) * b
to guarantee that.
