Least common multiple
Returns the least common multiple of a list of numbers.
- Use
functools.reduce()
,math.gcd()
andlcm(x, y) = x * y / gcd(x, y)
over the given list.
from functools import reduce from math import gcd def lcm(numbers): return reduce((lambda x, y: int(x * y / gcd(x, y))), numbers) lcm([12, 7]) # 84 lcm([1, 3, 4, 5]) # 60
