Best Answer

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.

There can't be any such number.' 4 ' itself is divisible by 2, so any number divisible by 4 must also be divisible by 2.

Yes, any number that is divisible by 4 is also divisible by 2.

4 is divisible by 1, 2 and 4. So is 8. If a number is divisible by 8, it will also be divisible by 4.

A number that is divisible by 2 is not always evenly divisible by 6. It must also be divisible by 3, and must not be smaller than 6. The numbers 2, 4, 8, 10, 14, 16, 20, 22, 26, and 28 etc. are all divisible by 2 but not (evenly) by 6. The opposite is true, though. Any number divisible by 6 is also divisible by 2.

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.

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.

Yes, any number that is divisible by 4 is also divisible by 2.

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.

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.

Not always for example, 36 is not divisible by 8 but it is divisible by 2 and 4.

4 is divisible by 1, 2 and 4. So is 8. If a number is divisible by 8, it will also be divisible by 4.

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.

The number 4 is divisible and it's divisible by 2.

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.
