What are the divisibility rules?
The Divisibility Rules
- Any integer (not a fraction) is divisible by 1.
- The last digit is even (0,2,4,6,8)
- The sum of the digits is divisible by 3.
- The last 2 digits are divisible by 4.
- The last digit is 0 or 5.
- Is even and is divisible by 3 (it passes both the 2 rule and 3 rule above)
What is the divisibility rule of 43?
Add thirteen times the last digit to the remaining leading truncated number. If the result is divisible by 43, then so was the first number. Apply this rule over and over again as necessary. Example: 3182–>318+13*2=344–>34+13*4=86 which is recognisably twice 43, and so 3182 is also divisible by 43.
