1:12 PM so i really wanted to try this whole prime factorization thing where can i find a number... there's gotta be a good number some where. ah, yes the date. 2615. thats four digits which seems kind of boring but since this is my first go at this its fine. clearly there's 5. 2+6+1+5 = 14. 2, 3, and 9 are out. 2615/5 = 523. shoot, i used a calculator for that, which defeats the whole purpose of the exercise and makes everything boring. i wont do it again, but i won't do it here either in the future 7: 523+7 = 530 --> 53. i think that has 7? 7 14 21 28 35 42 49 NOPE. 56. far and no cigar. no even close. 7 is way, way out. 11. okay, so this one is already trying to cross the hundred barrier. luckily its 11 so this shouldn't be too hard to solve. 523+77 = 590 --> 59. 11 is out. 13. 523 - 13 = 510. oh shoot, this is looking like 17 is in. but we aren't there yet. right? cross that bridge when we get there. im pretty bad at this because its my first time. 13 26 39 52. CLOSE but no cigar. 17. 523 + 17 = 540 yeah no 17 is NOT in. we actually i think should know it is NOT in because working with 13 we get a multiple of 17 which i think rules it out immediately. are we done? i think we might be done. 23 23 -- 69 460 --- over a thousand??? thats way wrong. what the fuck. clearly i have forgotten this method of 2nd grade math. ok, i figured it out. i forgot i was in a text editor. lets try that again. 23 23 -- 69 460 --- 529. so we're done. huh. 5*523 = 2615. kind of boring, but okay. i'll give this another go later 3:21 PM ANOTHER GO lets do it with the month day and time. from the bottom up. minute, hour, day, month. 21351. oh my goodness. 2 is out. 2 + 1 + 3 + 5 + 1 = 9. 3 is in, matter of fact there's 3x3. 21351 / 9. lets not calculator this time. 237 ------- 9 | 21351 18 --------- 3351 27 --------- 651 63 --------- 21 uh oh this is not going to work out. what's happened here. sigh. take 2. 9 is out i guess. 7117 ---------- 3 | 21351 21 ---------- 351 3 ---------- 51 3 21 21 ---------- 0! yay 7117. now there's an interesting number. a second 3 is out, but we already knew that. 5 is out. 7. i think we can work from the left. i also think that working from the left is a good idea. 117. am i allowed to work from BOTH SIDES AT ONCE??? i honestly don't see why not because no matter what order i do it in i can reach just good ol' 11, which is definitely not a multiple of 7. 7 is out. i think. id love for some later check to prove me wrong (i hope this isn't seriously a prime 4 digit) 11. 7117+33 = 7150 --> 715. that sucks, let's work from the left. 7117 - oh, christ, 7700. that puts us square in the negatives. that's never gonna work. ok, fine. i think i can just recurse this method. 715 + 55 = 770 --> 77. holy fucking shit. 11 is in. now we're getting somewhere. 647 ------- 11 | 7117 66 ------- 51 44 ------- 77 77 ------- 0 647. okay, lets crack this baby open. 647 + 13 --> 66, there's like no way right. 13 26 39 52 65. sorry buddy. 17. 63. nope. 19. 647 - 37 --> 61. nope. 23. 67. nope. 27. lets use 203. 647 + 203 = 850 --> 85. that's not gonna be even close. 27, 54, 81, yeah no way. i think we're done by now. 31 31 -- 31 930. yeah, we're done. 3*11*647 = 21351. that was a good romp. ROUND 3 WITH THE DATE OF DEAN'S OFFICE MOJITOPOP 1021. im gonna keep my promise even though the day isnt specified. 2 is out. 3 is out. 5 is out. 7 is out based on 10. 11. 101. 99 is local. 11 is out. 13*3=39. 106. uhhh. oh man, i gotta find a fast way to do this. 13*5 = 65 so 13*4 = 52. still doesn't help us yet. 78, 91, 104. 13 is out. 17. 51 pushes us below the thousand barrier, fuck that. lets just keep going and go from the left. 68, 85, 102. WOAH. that leaves just 1, so 17 is just barely out. 19. 104, man this one is really annoying. 95, 114. 19 is out. 23. lets use 299. 1021 299 ---- 1320, or 132. 115 is established. wait, i think this works and i should have realized it as soon as i saw 115. 23 more is 132. so 23 is in!! how many 23s though. 004 ------ 23 | 1021 92 ----- 101 i dont fucking understand. what??? 23 is NOT in. but i can also prove that it IS in. where did i go wrong, what is even true anymore. christ, let's just try 69. i didnt have a reason to go to 299 in the first place. 1021 + 69 = 1090 or 109. so 23 is definitely, totally out. wow. coulda been that simple. SO WHERE'D I MESS UP?? my addition seems solid. oh, for the love of god, i applied subtractive logic to the second digit and additive logic to the first digit to FORCE it to work. im just the brightest aren't i. point is, 23 is way out. good riddance! 29. we're still working with 1021. 105. thats a multiple of 7, so 29 is out. 31. ok, lets go from the left. 31, 62, 93. we can work with 102 - 93 = 9. so 91 is clearly ruling out 31. 37... 37, 74. and 3 -- 111. we already knew that but ok, too much. 102 74 --- 28. now we have 281. 281 - 111 = 170, so 17. 37 is way out. what even is the next prime number? is it 43? its 43. nevermind, 41 is also prime. so... 41. 102 82 --- 20. 201. 41, 82, 123, 164, 203. 41 is out. omg this is getting ridiculous. 43. 102 - 86 = 16. 161. 43, 86, 129, 129 43 --- 172. 43 is OUT. 47. 1021 i okay, so i just checked, and 47^2 is well over 2000. IS 1021 ACTUALLY A PRIME NUMBER??? OH MY GOD. I RANDOMLY CHOSE A PRIME NUMBER WELL. THAT EXPLAINS IT DOESN'T IT??? HAHAHAHAHAHAHA. 1021*1 = 1021. what a saucy one. wow, really broke that one down.
