NAME

6       factor - obtain the prime factors of a number
7

SYNOPSIS

9       factor [integer]
10
11

DESCRIPTION

13       factor  writes  to  standard  input  all prime factors for any positive
14       integer less than or equal to 10^14. The prime factors are written  the
15       proper number of times.
16
17
18       If  factor  is  used without an argument, it waits for an integer to be
19       entered. After entry of the integer, it factors it,  writes  its  prime
20       factors the proper number of times, and then waits for another integer.
21       factor exits if a 0 or any non-numeric character is entered.
22
23
24       If factor is invoked with an argument (integer), it writes the integer,
25       factors  it  and  writes  all the prime factors as described above, and
26       then exits. If the argument is 0 or non-numeric, factor writes a 0  and
27       then exits.
28
29
30       The maximum time to factor an integer is proportional to sqrt(n), where
31       n is the integer which is entered. factor will take this time when n is
32       prime or the square of a prime.
33

OPERANDS

35       integer    Any positive integer less than or equal to 10^14.
