Dear Number Theorist, Calculator, chris atkins mcs
bcc;
what do you like to buy at the shop or supermarket?
or how many piles of $$$ lottery do no gamb.

look up... 'corn rj 569-5037 '. factor
=47 X 12 1171 primes
the answer !
but try further approx.
# 185*655 = 12 1175 poor.
~ 47*2291*5289 = 569 5036.53
= 3*41*43*29*79*47. very close
021 595 759 artia ??? mob. the next phon num.
almost prime ??
# 11*19*43*89*27 = 21 595 761 very close +2....
= 4665 ^2 - 408^2. etc. approx.
977 9343 = 3*7* [259*1798+1]
= 465 683 = 738^2 - 281^2
= 21*457*1019 exactly prime factors ?
21= 3*7 > obvious.
programs don.mcdonald
n RND - FRAC STORE D
L = rational division a b/c.
repeat ALPHA D L ( RCL D L ANS +2
= = ...
if integer
ALP D L ANS = [p] STO D
/ [P] = = ... until fraction
if integer ANS STO D / [P] then repeat above etc.
i hope you get the hang of it.
try divide by 3.
if it does not divide evenly then
times 3/5
times 5/7
times 7/11 and so on.
myprogs program iterates these steps with a simple = = =...
Fermat's method N = A^2 - B^2. = (A-B) X ( A+ B).
SQRT D test square? round up
integer
V ( A^2 - RCL D )=
V ( ( V ( ANS ^ 2 + RCL D ) +1 )^2 - RCL D
= = ... hope for [near ] integer or easy rational B.
...oops shouldnt that [deleted] be the following.. CORRECTION.. -
Quote: SQR ( B^2 + RCL D) = [ A]
plus not minus. shows i am checking.
Quote: D = ( A - B) X ( A + B.) factorise.
quite easy pencil and paper. I did these for any phon> nums ( R Yee.)
or favourite food phone book.
*** invite me to demonstrate. you would see it easier.

so then.........look up... 'corn rj 569-5037 '.
FACTORISE =47 X 12 1171 primes the answer
the following is an earlier version. just as good.
the post [above message] is improved
BUT needs to hit **reveal quoted** portions.
....
but try further approx.
# 185*655 = 12 1175 poor.
~ 47*2291*5289 = 569 5036.53
= 3*41*43*29*79*47. very close

calc quadratic surd if you wish an unconscious random number.
enter..
n RND - FRAC STORE D
L = rational division a b/c.
repeat ALPHA D L ( RCL D L ANS +2
= = ...
if integer
ALP D L ANS = [p] STO D
/ [P] = = ... until fraction
if integer ANS STO D / [P] then repeat above etc.

brilliant, do you know?
Fermat's method N = A^2 - B^2. = (A-B) X ( A+ B).
SQRT D test square? round up integer
V ( A^2 - RCL D )
V ( ( V ( ANS ^ 2 + RCL D ) +1 )^2 - RCL D
= = ... hope for [near ] integer or easy rational B.
SQR ( B^2 + .. RCL D) = [ A] n.b. some versions have -ve error.
D = ( A - B) X ( A + B.) factorise.
quite easy pencil and paper. I did these for any phon nums
or favourite food phone book.
invite me to demonstrate.
cheers, kind regards,

e.g. powerball ## 11 65, sat 3-10-09 samoa 8.3 tsunami
e.g. 5*7*9* 41*241 = 31 1 25 [15] strike 5.
1 winner $ 22 206 973. almost prime ??
e.g. 14 144 5.6879 x 157 interesting sequence =n+ .0003 [456 789]
e.g. 23*27*240*149 = 222 06 960 very close
e.g. 125 463.1243 x 177 intg seq =n+ .0011. [123 456. 1234]
these are fair demonstration to spot the curious and unique.
therefore 74 % x lotto lines are doubled as powerball entry 1-10
with o.o5 % chance of collecting.
= 1918 / [40 choose 6] = 137/ 274 170.
63192 lotto winner div 3-6.
4674 powerball winner div 3-6. = 74 per mille. |
