What is the divisibility rule for 27?
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.
Is 4788 divisible by 9?

How many prime numbers are there between 20 and 200 end with an 8?
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".
A number is divisible by 8 the number formed by its last?
If the last three digits of a number are divisible by 8, the whole number is divisible by 8.
Is 1 2 3 5 9 or 20 divisible by 15345?
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.
What is the LCM of 27 10 12 and 8?
Well, because it has to be a multiple of 10, you know that it has to end with a 10. The 27 is the biggest number and will be what we focus on. To get the 27 into a multiple of 10, we have to multiply it by 10.10 x 27 = 270.270 is not divisible by 12 or 8, so we continue.Keeping in mind that the number has to be a multiple of 10 and 27, we can only add intervals of 270.270+270 = 540.540 is divisible by 27, 10 and 12, but not by 8. So lets add another 270.540+270 = 810810 is only divisible by 10 and 27, much like 270, so lets add another 270.810+270 = 10801080 is divisible by 27, 10, 12 and 8 and is the lowest common multiple.
What is a number divisible by 4?
It means that 4 can divide into a number evenly.4, 8, 12, 16, 20...Any multiple of 4 is divisible by 4.
What is the smallest number divisible by 8?
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.
If 4 is divisible by a number will 8 be too?
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.
