Just for fun, using Python, the exact value seems to be
$73239622318952846593863874519042298829761338251289259046349190034596307420803713$

Edit: Here's the code I used (as requested by Dorde):
def gcd(a,b):
c,d=a,b
while d>0:
c,d = d, c%d
return c
def lcm(a,b):
return a*b//gcd(a,b)
lcm_1_to_500 = 1
for i in range(2,501):
lcm_1_to_500 = lcm(lcm_1_to_500,i)
print(lcm_1_to_500)
