How to use a counter with a loop

How do you use a counter with a for loop?

I want to learn how to input a bunch of numbers into a loop and use the counter to find how many "count numbers" I get for that input. Whichever input gets the largest "count number" I want to save that input and display it.

hi,

here is fast way :

 N=1:1000;
 P=isprime(N);
 Prime=find(P==1);

Thank you, but that's not what I'm looking for. I want he program to take an "x" value, that is, from 1:999. For example, 132. I want the program to divide 132 by c ( 132/2, 132/3, 132/5...) If there are no remainders after division for each of these numbers, 1 is added to the counter. The number x that produces the greatest count number is the value that I want to keep. I hope this is clear.

hi, according to this description here is the translation :

 N=1000;
c=[2 3 5 7 11 13];
counter=0;
ctr=1;
for x=1:N

    if sum(rem(x,c))==0

        counter=counter+1;
        P(ctr)=x;
        ctr=ctr+1;
    else
        continue;
    end
end

But logically that s not right . counter is 0 .

hi,

Second way :

 K=primes(1000);

Third way :

N=1000;
c=[2 3 5 7];
counter=1;
for x=1:N

    V=mod(x,c);
    F=V(V==0);
    if isempty(F)

        Prime(counter)=x;
        counter=counter+1;
    else
        continue;
    end
end
