MATLAB: How to determine if a number is prime

homeworkloopsnumberprime

Hello, I was wondering if you can help how to determine if numbers from 0 to 100 are prime. Should I use loops? Please I am really confused with this homework.

Best Answer

thats not difficult .try to solve it on paper first .for example u have a number 100 . how will u check that its prime or not ?

divide it with all numbers from 1 to 99 .. and if any time the remainder is zero its not a prime number

to divide 100 from 1 to 100 u can use for loop .

Just as an obvious change:

n = 1;
x = 10001;
while length(primes(n)))<x
    n = n + 1;
end
n

This can definitely be improved still further.

sum(primes(500))

n = [2,3:2:500];
sum(n(sum(tril(rem(n(:),n(:)')) > 0,2)==(1:numel(n))'-1))
