:: If 1 is deemed to be a factor of 42, then so must 42 be; [[wp:Divisor|Wikipedia]] agrees with me. I've never heard of anyone defining factors for anything other than positive integers and in terms of positive integers; if I remember my schooling, it's usually a lead-in to talking about prime numbers.

The first sentence should be "Find the factors of a positive integer.", as the second sentence goes on to define what the factors are of a positive integer, not a number. -- [[User:Gerard Schildberger|Gerard Schildberger]] 04:57, 30 April 2012 (UTC) |

Should this be "Basic language learning"? I don't even know. Oligomous 12:10, 15 August 2009 (UTC)
This is a bit too similar to Prime decomposition for my taste. --IanOsgood 15:48, 15 August 2009 (UTC)
The Clojure, Python, Ruby and Tcl examples are all wrong; they omit the number itself which is always a factor (just as 1 is). Oops! --Donal Fellows (not logging in on this computer; don't own it...)
- No they are not wrong as such, the task description is very woolly. Do we mean integer factors? What about negative factors? Do we include zero?
- The task specification needs to be tightened up, so following what was given would most likely fit what was envisaged, but I should have flaagged for clarification. --Paddy3118 03:19, 16 August 2009 (UTC)

task description
The first sentence should be "Find the factors of a positive integer.", as the second sentence goes on to define what the factors are of a positive integer, not a number. -- Gerard Schildberger 04:57, 30 April 2012 (UTC)
