1 .TH FACTOR 1 2 .CT 1 numbers 3 .SH NAME 4 factor, primes \- factor a number, generate large primes 5 .SH SYNOPSIS 6 .B factor 7 [ 8 .I number 9 ] 10 .PP 11 .B primes 12 [ 13 .I start 14 [ 15 .I finish 16 ] 17 ] 18 .SH DESCRIPTION 19 .I Factor 20 prints 21 .I number 22 and its prime factors, 23 each repeated the proper number of times. 24 The number must be positive and less than 25 .if n 2**54 26 .if t 2\u\s754\s0\d 27 (about 28 .if n 1.8e16) 29 .if t 1.8\(mu10\u\s716\s0\d\|). 30 .PP 31 If no 32 .I number 33 is given, 34 .I factor 35 reads a stream of numbers from the standard input and factors them. 36 It exits on any input not a positive integer. 37 Maximum running time is proportional to 38 .if n sqrt(n). 39 .if t .I \(sr\o'n\(rn'\f1. 40 .PP 41 .PP 42 .I Primes 43 prints the prime numbers ranging from 44 .I start 45 to 46 .IR finish , 47 where 48 .I start 49 and 50 .I finish 51 are positive numbers less than 52 .if n 2**56. 53 .if t 2\u\s756\s0\d. 54 If 55 .I finish 56 is missing, 57 .I primes 58 prints without end; 59 if 60 .I start 61 is missing, it reads the starting number from the 62 standard input. 63 .SH SOURCE 64 .B \*9/src/cmd/factor.c 65 .br 66 .B \*9/src/cmd/primes.c
