Cannot print ULONG_MAX?

I am trying to print out these variables from the limits.h file, and all of them work, except the ULONG_MAX variable. It keeps printing out as 9223372036854775807 rather than 18446744073709551615. Not quite sure what is wrong here - I am pretty new to C.

#include <stdio.h>
#include <stdlib.h>
#include <limits.h>



int main(int argc,char **argv) {
    printf("Value     8   16     32     64\n");
    printf("UMax      0xFF    0xFFFF 0xFFFFFFFF 0xFFFFFFFFFFFFFFFF\n");
    printf("      %d      %d     %u %u\n", UCHAR_MAX, USHRT_MAX, UINT_MAX, ULONG_MAX);
    return 0;
}
