import math
def prime(x) -> bool:
y = int(math.sqrt(x))
for i in range(2, y + 1):
if x % i == 0:
return False
return True
t = int(input())
while t > 0:
t -= 1
n = int(input())
s = 1
p = 1
q = 1
for i in range(2, 10000):
if prime(i):
s *= i
if s > n:
break
p = p * i
q = q * (i + 1)
gcd = math.gcd(p, q)
p //= gcd
q //= gcd
print(f"{p}/{q}")
这程序好像有点Bug，我给组数据试试？
