Weird output and calling to another function

I'm having weird issues with a weird output of ans = 1 from this code

function m = primefactors(m)
k=zeros(1,m);
x = 2;

while m>1
    if mod (m,x) == 0
        m=m/x;
        k(end+1)=x;
    else
        x=x+1;
    end
end
z=k(k~=0);
disp(z)
end

I'm then also trying to store those outputs into another function but i'm not sure how

function g = RSA(n,e)
    [p,q] = primefactors(n);
    disp(p)
    disp(q)
end

What is this?

It appears to be a tiny, tiny image that is impossible to read unless I zoom the entire web page to around 500%. :) Can you make it bigger?

What do you mean by "storing p and q into another function"? Can you elaborate?

That's because you are returning m. I think you want to return z:

function z = primefactors(m)
