1. Any number is divisible by 2 if the last digit is even. For example,4726658 is divisible by 2.
2. Any number is divisible by 3 if the sum of all the digit of that number is divisible by 3. For example - 2343681, the sum of the digits of this number is equal to 2+3+4+3+6+8+1= 27, which is divisible by 3.Hence the number 2343681 is divisible by 3.
3. Any number is divisible by four if the last two digits of the number are divisible by 4. For example - 23456780 is divisible by four because it's the last two-digit, i.e., 80 of the given number is divisible by 4.Hence the number 23456780 is divisible by 4.
4. Any number is divisible by five if the last digit of the number is either 5 or 0. For example - 2789405 is divisible by 5 since the last digit of the number is 5.
