There is no easy rule for divisibility by 34.

The divisibility rules of 4 and 9 are combined to make the divisibility rule of 36.

By tautology. If it did not work, it would not be a divisibility rule!

there is a divisibility for 24 the rule is you can divide 24 as 6 and 4 i think

The divisibility rule for 2 works because the base of our number system, 10, is divisible by 2.

The divisibility rule for 22 is that the number is divisible by 2 and by 11. Divisibility by 2 requires that the number ends in 0, 2, 4, 6 or 8. Divisibility by 11 requires that the difference between the sum of the the digits in odd positions and the sum of all the digits in even positions is 0 or divisible by 11.

A divisibility rule is a statement of procedures to determine divisibility. For example:"A number is divisible by 2 if it ends with 0, 2, 4, 6 or 8".It does not make any sense to divide such a sentence by 2 or 895 or any other number!

the number is even.

It has to end 00.

it is divisible by5

It is 86

The rule for 1 and the rule for 3.

Judging by some of the questions asked on this site, the first rule is that divisibility is a concept that applies only to whole numbers.

2 squared 1 = 4 so the divisibility rule is that it is divisible by 1, 2 and 4.

A number is divisible by 8 if and only if it is an integer and the last three digits make a number that is divisible by 8. A general divisibility rule for 2^n where n is an integer is to take the last n digits and if they make a number that is divisible by n then it is divisible by n.

By using the divisibility rule for 3, we find that 117 is divisible by 3. That makes it composite.

it is divisible by 3 and 9
