Integer Max  Working on a Project Euler problem and the question
asks for the largest prime number that is a factor of
600851475143. As you can see, this is significantly larger than
the maximum of a long data type, which maxes out at 2147483647.
Any ideas around this?  I'm running on Windows 32, so int64 is
not a valid option for me. It seems like I'll likely have to use
a different language to solve this problem. have u tried using
int64? Use a bignum library. have you tried using long long int?
sizeof (__int64) = sizeof (long long int) = 8 using MinGW X86,
so it will work in your case. Topic archived. No new replies
