Using divisibility tests, determine the following number is divisible by $$4$$; by $$8$$.
$$2150$$.
$$2150$$ is not divisible by $$4$$ because the number formed by the last two digits $$(50)$$ is not divisible by $$4.$$
$$2150$$ is not divisible by $$8$$ because the number formed by the last three digits $$(150)$$ is not divisible by $$8$$.
