False. Consider 4, itself.
Not always for example, 36 is not divisible by 8 but it is divisible by 2 and 4.
All the numbers that are divisible by 8 are 1,2,and 4
yes.. always..
Add up the digits---5+2+7+8 22 which is NOT a multiple of 3 so it is NOT divisible by 3. == Here is a list of the divisibility rules: 2 If the last digit is even, the number is divisible by 2. 3 If the sum of the digits is divisible by 3, the number is also. 4 If the last two digits form a number divisible by 4, the number is also. 5 If the last digit is a 5 or a 0, the number is divisible by 5. 6 If the number is divisible by both 3 and 2, it is also divisible by 6. 7Take the last digit, double it, and subtract it from the rest of the number;if the answer is divisible by 7 (including 0), then the number is also. 8If the last three digits form a number divisible by 8,then so is the whole number. 9 If the sum of the digits is divisible by 9, the number is also. 10 If the number ends in 0, it is divisible by 10. 11 Alternately add and subtract the digits from left to right. (You can think of the first digit as being 'added' to zero.)If the result (including 0) is divisible by 11, the number is also.Example: to see whether 365167484 is divisible by 11, start by subtracting:[0+]3-6+5-1+6-7+4-8+4 = 0; therefore 365167484 is divisible by 11. 12 If the number is divisible by both 3 and 4, it is also divisible by 12. 13Delete the last digit from the number, then subtract 9 times the deleteddigit from the remaining number. If what is left is divisible by 13,then so is the original number
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. ■
False. Consider 4, itself.
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.
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.
Yes. 8 / 4 = 2 8 is also divisible by 2 and 8.
