yes.. always..

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.

There is no answer because for a number to be divisible by 8, it would end in an even number and therefore be divisible by 2.

The smallest number divisible by 2 4 6 8 10 12 14 is 840.

If the number formed by the last three digits is divisible by 8. Alternatively, if the number is divisible by 2, the quotient is divisible by 2 and that quotient is 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.

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.

Any number that ends with 0, 2, 4, 6, or 8 is divisible by 2.Any number that ends with 0, 2, 4, 6, or 8 is divisible by 2.Any number that ends with 0, 2, 4, 6, or 8 is divisible by 2.Any number that ends with 0, 2, 4, 6, or 8 is divisible by 2.

2 times 4 equals 8. 8 is divisible by 2 and 4, but 2 and 4 are NOT divisible by 8. 8 is a multiple of 2 and 4. If you want to be technical, any number (other than zero) is divisible by any number. I assume you mean divisible evenly, in which case the above answer will answer your question.

Of 2, 3, 4, 5, and 8, the smallest number divisible by 2 is 2.

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

yes.. always..

Look at 12. Not divisible by 8 but divisible by 4 and 2. Look at 4. Same thing. The equation 8x-4 will give you any number divisible by 4 and 2, but not 8 32 is divisable by all three. 8x4=32, 2x16=32

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.

8 = 2*4 1606 is divisible by 2 as it is an even number. Therefore, 1606/2 = 803. 803 is not divisible by 4 as it is odd. Therefore, 1606 is not divisible by 8.

No. A number is divisible by 2 if it ends with 0, 2, 4, 6 or 8.

Yes. To check if a number is divisible by 4, if the last 2 digits (as a number) are divisible by 4, so is the original number. 32 = 4 x 8 so as 32 is divisible by 4, so is 211032. An alternative test for 4: add the last digit to twice the preceding digit, and if this sum is divisible by 4 so is the original number. This can be repeated until a single digit remains which must be 4 or 8 (to be divisible by 4) if the original number is divisible by 4. for 211032: 2 + 3x2 = 8 → [single digit 8 which] is divisible by 4, so 211032 is also divisible by 4.
