Test the divisibility of the following number by $$3$$: $$474$$
Test the divisibility of the following number by $$3$$: $$378$$
we know that if the sum of digit of the number is divisible by $$3$$ then the number is divisible by $$3$$.
Sum of the digit of $$378$$ is $$18$$, which is divisible by $$3$$
$$\therefore$$ the given number $$378$$ is divisible by $$3$$.
