You can convert the number to a String then extract every char that is one of '1', '3' etc from that String.

Is this homework? I've pointed you in the right direction, now you have to do some work.

To convert an integer to a String:

int x = 1234567;
String str = "" + x;

Look up charAt in String class documentation for extracting individual characters from a string.
