Is it true that a number is divisible by 8 if it divisible by 4 and divisible by 2?

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.


If 4 is divisible by a number will 8 be too?

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.

Why isn't a number divisible by 8 if it divisible by both 4 and 2?

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


Is 211032 divisible by 4?

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.
