★. A number is divisible by 3 if the sum of its digits is divisible by 3.

$\Large\boxed{Example 1:-}$ Consider the number 64275.

Sum of its digits= (6+4+3+7+5)= 24, which is divisible by 3.

Therefore,64275 is divisible by 3.

$\Large\boxed{Example 2:-}$ Consider the number 39583.

Sum of its digits= (3+9+5+8+3)=28, which is not divisible by 3.

Therefore, 39583 is not divisible by 3.
