1, 3, 9, 27, 81.
Techcially all numbers are divisible by 81, however many would result in a decimal answer. If you mean how many numbers are divisible by 81 and have an integer answer, then it is "all multiples of 81" - e.g 81 x 2, 81 x 3 etc...81, 162, 243 and keep adding 81 forever.
1 and 9
Just the number 1.
The numbers are 1 and 3 with no remainders
170 * * * * * No. These are numbers of the form AB00 (9*9 = 81 of them) C0D0 (81 of them), and E00F (81 of them). 243 in all.
There is no GCF of 32 and 81 because no prime numbers go into either 32 or 81
Yes. The square root of 81 is 9 - a natural number and all natural numbers are rational numbers.
If you mean: 53 81 41 47 and 31 then 81 is a composite number while all the rest are prime numbers
