the divisibility rule for 2 is: The number is even;the last digit ends with a 2,4,6,8,10, etc.The divisibility rule fir 3 is: The sum of the number is divisible by 3The divisibility rule for 4 is: The last two digits are divisible by 4The divisibility rule for 5 is: The number ends with a 5 or 0The divisibility rule for 6 is: The sum CAN be divisible by 2 and or 3The divisibility rule for 9 is: The sum of the number is divisible by 9The divisibility rule for 10 is : The number ends with a 0

If the number is even, it's 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.

There is no easy rule for divisibility by 34.

The number must be divisible by 2 and by 7.

If the number is even, it's divisible by 2.

There is no divisibility rule for 13 because it is a prime number. If you are thinking: why is there a divsibility rule for 2 and 3 then. Well, i don't know so go look it up on google.

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!

Rule: If it is divisible by 2 and by 3Numbers are divisible by 6 if they are divisible by 3 and 2. Therefore, for example, since 18 is divisible by 3 and 2, it is also divisible by 6.The divisibility rule for 6 is, it can go into the number if 2 and 3 can also.

If the rules for 2 and 3 work, the number is divisibale by 5.

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

If the number is even it is divisible by 2. The number is even if its units digit is even, that is, if it is 0, 2, 4, 6 or 8.

the number is even.

Use the divisibility rule for 10. If the number is divisible by 10, then it is obviously also divisible by 5.

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.

There are two ways of answering this.Check the number for divisibility by 2.Check the quotient for divisibility by 2.Check the quotient for divisibility by 2.Check the quotient for divisibility by 2.Check the quotient for divisibility by 2.Check the quotient for divisibility by 2.For large numbers, the check can be restricted to the number formed by the last six digits.

The divisibility rule for 42 isdivisibility by 2, ANDdivisibility by 3, ANDdivisibility by 7.Divisibility by 2 requires the number to be even. That means it must end in 0, 2, 4, 6 or 8.Divisibility by 3 requires that the digital root of the number is divisible by 3. That is, the sum of the digits is divisible by 3. If the first sum is large, you can calculate the digital root of the digital root (and again, if necessary) and check that for divisibility by 3.The divisibility rule for 7 is more difficult.Take the last digit (units).From the number formed by the remaining digit, subtract twice the last digit.If the answer is divisible by 7 (including zero or negative numbers), then the original number is divisible by 7.For large numbers, repeat the process to bring the number down to a manageable size.

No, because the number is not even. The rule of divisibility for 2 is that the number must be even. 620123 is not even, so therefore, that number is not divisible by 2.

If a number ends in 0, it is divisible by 10.

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

2 is a prime number, so its only divisors are 1 and itself. Any other number having a divisibility of 2 is an even number.

If it ends in 2, 4, 6, 8, or 0 (zero), then it's divisible by 2.If it's an even number, it's divisible by 2.

The number must be divisible by 13 and by 11.

A number has to be even and also divisible by 3.
