Nobody canceled 64-bit numbers, @ Ivan Kushchev :

#include <stdio.h> int main() { long long i = 600851475143LL; printf("%lld\n", i); return 0; }

This may be important if the old version of Visual Studio on Windows is used, which poorly supports c99, which guarantees long long and that its size is at least 64-bit (you can try "% I64" and __int64 in this case).

Use another compiler that has 64-bit data types. Or the keys of the existing one.

Or use two variables, in one store n most significant digits, and in the other - Nn digits, where N is the total number of digits of the number.
