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 are the 10 divisibility rules?

A number is divisible by 10 if the last digit of the number is 0. The numbers 20, 40, 50, 170, and 990 are all divisible by 10 because their last digit is zero, 0. On the other hand, 21, 34, 127, and 468 are not divisible by 10 since they don’t end with zero.

## How many types of divisibility rules are there?

Divisibility rules for numbers 1–30 Divisor Divisibility condition 20 It is divisible by 10, and the tens digit is even. The number formed by the last two digits is divisible by 20. 21 Subtracting twice the last digit from the rest gives a multiple of 21. It is divisible by 3 and by 7.

## What are three divisibility rules?

According to the divisibility rule of 3, any big number is exactly divisible by 3 if the sum of the digits is a multiple of 3. For example, the number 2,146,497 is exactly divisible by 3, where quotient = 715,499 and remainder = 0. The sum of all digits is 2+1+4+6+4+9+7 = 33 and 33 is exactly divisible by 3.

## What are the divisibility rules for 2 3 5 and 10?

Here are the rules to test divisibility by 2, 3, 5 and 10. A number is divisible by 2 if it ends in 0, 2, 4, 6 or 8. This means that it is even. 3044 is therefore not divisible by 3, because 11 is not divisible by 3.

## What is the divisibility rule of 1 to 10?
