For the bonus question (on OSX):

words= textread('/usr/share/dict/words','%s');

for k=1:numel(words)
wordprod(k) = word_product(words{k});
end
[~,i] = min(abs(wordprod-1000000));
words{i}
wordprod(i)

% curing with word product of 1000188

Everett Rubel on 14 Oct 2012

For the bonus question, we can rule out any number that has a prime factor greater than 26 (z). The product found by Jason Friedman is the first number greater than 10^6 that does not have such a prime factor. The product 999856 is the largest number less than 10^6 to be part of a possible solution.

I like playing with strings and ASCII table ;)

Everett appears to miss the fact that 1000000 has no prime factors above 26, and Jason's dictionary doesn't seem to include obsolete words. 'tetty' scores a perfect 1000000.

John D'Errico on 20 Aug 2016

Well, if you happen to know someone named 'BettyJ', thus a first name of Betty, last initial J, this works: word_product('BettyJ').

Nice problem

Can you give me a hint on how to program the bonus question? I used factor but that is not a good way.

Joel Hottinger on 8 Jul 2021

If we can include multiple words in our bonus answer, the word "tea" 3 times scores perfect. n = 'teateatea'

'curing' returns 1000188.

Stephen Cook on 23 Mar 2017

Closest 10 words are 'curing', 'Nicaragua', 'comers', 'Moors', 'rooms', 'banquet', 'Arkansas', 'sulks', 'alkaline' and 'Canaveral'.

Words that make 1000,000, tetty and typey apparently, :)

'j' corresponds to 10 according to the code above so, the word that gives exaclty 1E+6 is 'jjjjjj'
% word_product('jjjjjj')=1E+6

Sylvain on 13 Mar 2013

I don't think that 'jjjjjj' is really a word...
