WebThe divisibility rule of 3 states that a whole number is said to be divisible by 3 if the sum of all its digits is exactly divided by 3. Without performing division we can find out whether a number is divisible by 3 or not. For example, 45 is divisible by 3 because the sum of 45 is (4 + 5) = 9, which is divisible by 3.
WebDivisibility rule of 25 states that when the last two digits formed are 00, 25, 50, and 75 then it is divisible by 25. Here, the last two digits are 78 which is not divisible by 25. Thus, 5678 is not divisible by 25.
