Generate Mulitple of specific integer with NaturalGenerator

[KEN-00]

Hi . I would like to ask is there a way to generate a random natural number which is a multiple of a specific factor n?

For example:

int factor = 3;
NaturalGenerator naturalGenerator = JRand.natural();
naturalGenerator.min(0);
naturalGenerator.max(999);
//do something with factor
int randomMultiple = naturalGenerator.gen();
