Why is a number that is divisible by 8 also divisible by 4?
Because 8 is divisible by 4. So of course if 8 goes into a number, 4 will too. The number 24 for example. 8 * 3 = 24 and 4 * 6 = 24. 4 is half of 8. So 4 can go into anything 8 can, but twice as many times.
How do i find out if a number is divisible by 4 or 8?
If the number is a multiple of 4 or 8 then it is divisible by 4 and 8 with no remainder If a number can be halved and the answer is even, it was divisible by 4.If the number can be halved twice and the answer is stilleven, it was divisble by 8.
Is a number divisible by 4 also a divisible by 8?
Every other number: 8, 16, 24, 32, 40... No, a number can be divisible by 4 but not divisible by 8; an example is 12.
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.
What are the divisibility rules for numbers 4 6 and 8?
For 4:Are the last two digits in your number divisible by 4? If so, the number is too! For example: 358912 ends in 12 which is divisible by 4, thus so is 358912. For 6: The number must be divisible by 2 and 3. For 8: This one's not as easy, if the last 3 digits are divisible by 8, so is the entire number. Example: 6008 - The last 3 digits are divisible by 8, therefore, so is 6008.

What is the divisiblity rule for the number 8?
To find out if a number is divisible by 8 the number must be divisible by 2 and 4!
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.
Why are 2 and 4 divisible by 8?
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.
