Write function script that accepts a value which should be prime factorized. The function script should output the respective factors of the input value.
Could someone help me with what this would look like in terms of code using loops/conditional statements?

function pfactors=pfactor(x)
pfactors=[];
for k=primes(x)
while mod(x,k)==0
pfactors=[pfactors,k];
x=x/k;
end
end
end

Thank you! Could you rewrite your code without using primes() command by any chance?

for k=2:x
while mod(x,k)==0
