Divisibility Rules for 2, 4, 5, 10, 3, 9

To determine the divisibility of a number by 2, 4, 5, 10, 3, and 9, there are specific rules and patterns to consider.

Divisibility by 2: A number is divisible by 2 if its last digit is even (0, 2, 4, 6, 8).

Divisibility by 4: A number is divisible by 4 if the number formed by its last two digits is divisible by 4.

Divisibility by 5: A number is divisible by 5 if its last digit is 0 or 5.

Divisibility by 10: A number is divisible by 10 if it ends with 0.

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

Divisibility by 9: A number is divisible by 9 if the sum of its digits is divisible by 9.
