Subtract 8 times the last digit from remaining truncated number. Repeat the step as necessary. If the absolute of result is divisible by 27, the original number is also divisible by 27 Check for 945: 94-(8*5)=54; 5-(8*4)=-27 Since 27 is divisible by 27, the original no. 945 is also divisible. Check for 264681: 26468-(8*1)=26460; 2646-(8*8)=2582; 264-(8*6)=216 21-(8*6)=-27 Since 27 is divisible by 27, the original no. 264681 is also divisible. Check for 81: 8-(8*1)=0; Since 0 is divisible by 27, the original no. 81 is also divisible.
The easiest way to know if a number is divisible by 9 is to add the digits in the number. 4 + 7 + 8 + 8 = 27 Since 9 will go into 27 evenly, 4788 is divisible by 9.
No number between 20 and 40 is divisible by all 4 numbers. The smallest number divisible by all 4 of those numbers is: 56
If the last 3 digits are divisible by 8, the number is divisible by 8.
40 is divisible by 1, 2, 4, 5, 8, 10, 20 and 40.
None. A number that ends with 8 is even, that is, divisible by 2. ================================ To be prime a number must only be divisible by itself and 1 thus any number divisible by 2 can not be a prime number. Therefore the answer to your question is:- "There are no prime numbers between 20 and 200 that end with an 8".
If the last three digits of a number are divisible by 8, the whole number is divisible by 8.
Well, honey, a number that is divisible by both 4 and 10 is 20. Now, if you want a number that has a difference of 8 from 20, just add 8 to it and you get 28. So, the number you're looking for is 28. Easy peasy lemon squeezy!
A number is divisible by another number is, after dividing by that number, the answer is an integer with no remainder left over. For this reason, no number can be divisible by a number greater than itself. Thus, neither 1, nor 2, 3, 5, 8 or 20 are divisible by 15,345.
It means that 4 can divide into a number evenly.4, 8, 12, 16, 20...Any multiple of 4 is divisible by 4.
There is no smallest number since if any number is divisible by 8, then 8 less than that number is also divisible by 8 - and that argument continues all the way to minus infinity!The smallest positive number divisible by 8 is 8, itself.
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.
