The prime factors of 13195 are 5, 7, 13 and 29.
What is the largest prime factor of the number being input, input might be uint64 for large numbers, out must be double precision?
Thank you to Project Euler Problem 3
why it is not accepting the answer ;we cant make such small solutions we are not like professional coder
still something fishy with the 3rd problem, example:
x = uint64(321676750829977632);
num2str(x) -> 321676750829977600
rem(x,10) -> 0
euler003(x) -> 83653987
ok now, it seems this was only an issue with my matlab version (7.7) but was not present in the version running the solvers (which seems to have uint64 arithmetic supported!, man, I need an upgrade...)
You should pass the x values as a string. A double precision number cannot resolve all the digits that one needs to solve the test suite problems:
>> x = 321676750829977632;
>> x == x+1
I agree that there is an issue with the last test suite problem. passing it as a uint64 would work too.
Yep I got "Error: Out of memory. Type HELP MEMORY for your options." :-)
