Answer 1

Answer:

40872 is completely divisible by 3

Step-by-step explanation:

The divisibility rule for 3 goes as follows-

Any number is divisible by 3 if the sum of all its digits adds up to a number that completely divides by 3 without leaving a remainder.

The number given here is - 40872

to check if 40872 is divisible by 3, we follow this procedure-
