Divisibility Rules

Divisibility by 2:
- A number is divisible by 2 if it is even, which includes all numbers ending in 0, 2, 4, 6, or 8.
Divisibility by 3:
- Sum all the digits of the number. If the total is divisible by 3, then the original number is also divisible by 3.
- Example: For 12123, 1+2+1+2+3=9. Since 9 is divisible by 3, so is 12123.
Divisibility by 4:
- Check if the last two digits of the number are divisible by 4. If they are, the entire number is also divisible by 4.
- Example: In 358912, the last two digits (12) are divisible by 4, so 358912 is divisible by 4.
Divisibility by 5:
- A number is divisible by 5 if it ends in 0 or 5.
Divisibility by 6:
- A number is divisible by 6 if it is divisible by both 2 and 3.
Divisibility by 9:
- Similar to the rule for 3, sum all the digits. If the total is divisible by 9, so is the original number.
- Example: For 43785, 4+3+7+8+5=27. Since 27 is divisible by 9, so is 43785.
Divisibility by 10:
- If a number ends in 0, it is divisible by 10.
