Answer:
A number is divisible by 4 if the last 2 digits are evenly divisible by 4 or if it is divisible by 2 twice and the quotient is a whole number. A number is divisible by 8 if the last 3 digits are evenly divisible by 8 or if it is divisible by 2 three times and the quotient is a whole number.
Numbers which are divisible by both 2 and 3 are divisible by 6. That is, if the last digit of the given number is even and the sum of its digits is a multiple of 3, then the given number is also a multiple of 6. Example: 630, the number is divisible by 2 as the last digit is 0.
