Buggy python submission (verdict: Runtime Error):
def lcm(x, y):
    return (x * y) // math.gcd(x, y)

import math
nm=list(map(int,input().split()))
a=list(map(int,input().split()))
lcm1=a[0]
for i in range(nm[0]-1):
    lcm1=lcm(lcm1, a[i+1])
answer=nm[1]//(lcm1)+1
print(answer)

Fixed submission:
import fractions
from functools import reduce
def lcm_base(x, y):
    return (x * y) // fractions.gcd(x, y)
def lcm_list(numbers):
    return reduce(lcm_base, numbers, 1)

a=list(map(int, input().split()))
