Being divisible by 4, means that it will also be divisible by 2, so that doesn't tell you anything about divisibility by 8. But if you divide the number by 2, and this quotient is divisible by 4, then yes the original number is divisible by 8.

Is there any number divisible by 2 but not 4?

Yes, half of the numbers divisible by 2 are not divisible by 4. For example, 2 is divisible by 2 but not by 4. The same is true for 6, 10, 14, 18, 22, 26, etc.


If a number is divisible by 2 and 4 then it is divisible by 8?

Not entirely. If the number is 4, then 4/2 = 2, and 4/4 = 1, but dividing by 8 does not produce a whole number. 4/8 = .5 or 1/2. This is not always true, but it can be true if the number is something like 32, where 32/2 = 16, 32/4 = 8, and 32/8 = 4.

That is not necessarily the case. 6 is divisible by 2, but not by 4.Actually, if the last two digits can be divisible by 4 then the whole number is divisible by 4. Hi! But if a number is divisible by four then it is divisible by 2. But not the other way around.


What is a number divisible by 4 but not by 2?

There are none. As a factor of 4, 2 is a factor of all numbers that are multiples of 4. The reverse comparison is true, however, because only half (exactly half) of the numbers divisible by 2 are also divisible by 4.

Why is that when a number is divisible by 2 and divisible by3 it is also by six how are they related why does this pattern not work for 2 4and 8?

Numbers divisible by 6 will have at least one 2 and one 3 as prime factors because 2 x 3 = 6. The same is true for 2, 4 and 8. Numbers divisible by 4 are also divisible by 2. Numbers divisible by 8 are also divisible by 4 and 2.

What is the divisibility rule for 4 and 6?

The Rule for 4 is if the last 2 numbers are divisible by 4 (The tens and ones place) For example. 10759283740 is divisible, while 10759283738 is not, because 4 does not go into 38. The rule for 6 is if the number is even and also divisible by 3. If this is true, then the number is divisible by 6.
