NAME
factor - prime-factor numbers
SYNOPSIS
factor <int> <int>-<int> ...
DESCRIPTION
The program will compute the prime factors of each number you give it
as an argument. If no arguments are given, it will read numbers from
standard input, one per line. In addition to simple integers, you can
also specify a range of integers as "<int>-<int>", or you can use up
to 3 trailing wildcards. Here are some examples:
% factor 223092871 2147483647
223092871 = 317 703763
2147483647 = 2147483647
% factor 65534-65538
65534 = 2 7 31 151
65535 = 3 5 17 257
65536 = 2^16
65537 = 65537
65538 = 2 3^2 11 331
% factor 123456789.
1234567890 = 2 3^2 5 3607 3803
1234567891 = 1234567891
1234567892 = 2^2 41 7527853
1234567893 = 3 13 31655587
1234567894 = 2 7 47 479 3917
1234567895 = 5 11 23 975943
1234567896 = 2^3 3 83 619763
1234567897 = 17 73 994817
1234567898 = 2 61 10119409
1234567899 = 3^4 109 139831
