if the number is divisible by 2 and 3 then it is divisible by 6 =D

The only number by which four is divisible is two.

it is a rule that is followed when wanting to see if a number can go into another number. ex: the divisibility rule for 3 is if the sum of the numbers is divisible by three then the whole number is divisible by 3. if the problem is 75, 3 can go into it because the sum of the numbers equals 12, look 7+5 = 12 . you can look up other divisibility rules on here but if found please answer my question.... what is the divisibility rule for 7? Hope that helped, me888100 p.s. this was written by a 13 yr old

why does the divisibility rule work for 4

There are infinitely many possible answers: Rule I: Output = 4 (whatever the input, the output is 4). Rule 2: Output = Input - 2 Rule 3: Output = Input/2 + 1 Rule 4: Output = (Input/3)2

To find out if a number is divisible by 8 the number must be divisible by 2 and 4!

if the number is divisible by 2 and 3 then it is divisible by 6 =D

No - because it's an odd number !

The only number by which four is divisible is two.

The rule to decide if a number is divisible by 9 is to look at the sum of the digits. If the sum of the digits is divisible by 9, then so is the number.

Add the digits together and if the result is divisible by 9, the original number is divisible by 9.

60.

-9

Just carry out the division, and see if you get an integer. It isn't worth the trouble to memorize or, worse, figure out divisibility rules for all sorts of large numbers.

A number is divisible by 15 if it is divisible by 5, and by 3. For example, 165 is divisible by 15, since it ends in 5, and the sum of its digits is divisible by 3.

If the sum of the digits is a multiple of 3, yhen the number is divisible by 3.

In most cases, it is easier to do the division than to use some special divisibility rule. Divisibility rules only save you time in some special cases, such as:2, 4, 8, 5, 10, 25 (look at the last digit or digits)3, 9 (add the digits, and see if it is divisible by 3 or by 9, respectively)7, 11, and 13 (separate the last three digits and subtract from the remaining number)
