Lesson 4
Divisibility rules-
Are rules that help determine whether the number is divisible by the rule number or not.
Divisibility rules-
Are rules that help determine whether the number is divisible by the rule number or not.
- Divisibility by 2: The number should have 0, 2, 4, 6 or 8 as last units digit.
- Divisibility by 3: The sum of digits of the number must be divisible by 3 .
- Divisibility by 4: The number formed by the tens and last digit of the number must be divisible by 4 .
- Divisibility by 5: The number should have 0 or 5 as the last digit.
- Divisibility by 6: The number should be divisible by both 2 and 3.
- Divisibility by 7: Take the last digit of the number, double it. Then subtract the result from the rest of the number. If the resulting number is evenly divisible by 7, so is the original number.
- Divisibility by 8: The number formed by the hundreds, tens and units digit of the number must be divisible by 8 .
- Divisibility by 9: The sum of digits of the number must be divisible by 9.
- Divisibility by 10: The number should have 0 as the units digit.
