If the number is even, it is divisible by 2.
If the sum of the digits is a multiple of 3, the whole number is divisible by 3.
Three
The divisibility rules of 4 and 9 are combined to make the divisibility rule of 36.
The answer will depend on the divisibility rules list.
fractions help you write out divisibility rules because divisibility rules help with fractions . Glad I would help good bye

The divisibility rules for a prime number is if it is ONLY divisible by 1, and itself.
Divisibility rules help you find the factors of a number. Once you've found the factors for two or more numbers, you can find what they have in common. Take 231 and 321. If you know the divisibility rules, you know that they are both divisible by 3, so 3 is a common factor.
If you know that a number is divisible by three, then you know that three and the number that results from the dividing are both factors of the original number. If you know that a number is not divisible by three, then you won't waste time performing that function. It's rare that the first factor other than one isn't a number between two and ten. If you know the divisibility rules, it will make factoring easier and faster.
Any multiple of two must end in 0, 2, 4, 6 or 8.

You can always check on the divisibility of a number by dividing it into another number. But if you know the divisibility rules, you can get that information easier and faster.
