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.
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.
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.
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.
4 divides 4 (once), but 4 is not divisible by 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.
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.

False. Consider 4, itself.
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.
4 x 4 = 16 2 x 8 = 16 8 x 4 = 32 4 x 8 = 32...
They can also be evenly divided by 1, 2 and 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.
Not always for example, 36 is not divisible by 8 but it is divisible by 2 and 4.
To determine if a number is divisible by 4, check if the last two digits form a number that is divisible by 4. For divisibility by 8, the last three digits of the number must be divisible by 8. Essentially, a number that meets the criteria for both divisibility by 4 and 8 will have its last two digits divisible by 4 and its last three digits divisible by 8.
Yes. 8 / 4 = 2 8 is also divisible by 2 and 8.
