450880 2006-04-30 09:11:00 what is the smallest even prime number?? robsonde (120)
450881 2006-04-30 09:23:00 2 gcarmich (10068)
450882 2006-04-30 09:25:00 oh - and all the rest are odd gcarmich (10068)
450883 2006-04-30 10:25:00 Hmm I don't really see what's interesting about that. roddy_boy (4115)
450884 2006-04-30 10:28:00 thing is that most people dont know that 2 is prime, they automaticly think that to prime it must be odd. robsonde (120)
450885 2006-04-30 10:31:00 2 is an odd number?

450886 2006-04-30 10:34:00 An integer greater than one is prime if its only positive divisors are itself and one

2 can only be divided by itself (2) and 1

robsonde was saying that most people assume all primes are odd, and hence a lot of people don't think 2 is prime. But it is.

Just to be pedantic, the actual definition of a prime is a natural number with exactly 2 unique natural factors.

450889 2006-04-30 10:48:00 1 + 2 = 3
4 + 5 + 6 = 7 + 8
9 + 10 + 11 + 12 = 13 + 14 + 15

Now this is interesting.
