no because 81 is an odd number. only even numbers are divisible by 2 evenly.
No, 81 is not divisible by 4. In order for a number to be divisible by 4, the last two digits must be divisible by 4. In this case, the last two digits of 81 are 81 itself, which is not divisible by 4. Therefore, 81 is not divisible by 4.
81 and 162 are both multiples of 3. In mathematics, a number that can be divided by another number without leaving a remainder is said to be divisible by that number. Both 81 and 162 can be evenly divided by 3, making them multiples of 3.
No. 81 is not evenly divisible by 16.
54, 63, 72, 81, 90, and 99 is.

No, 81 is not divisible by 4. In order for a number to be divisible by 4, the last two digits must be divisible by 4. In this case, the last two digits of 81 are 81 itself, which is not divisible by 4. Therefore, 81 is not divisible by 4.
Not always as for example 81 is divisible by 3 but not by 6
81 has factors other than 1 and itself, so it is not a prime number. For example, it is divisible by 3. (You can check this by adding the digits of the number: 8 + 1 = 9. If the sum of the digits is divisible by 3, the number is also divisible by 3.) Therefore, 81 is a composite number.
"What is divisible by 81?" Any multiple of 81 is divisible by 81. For example, all of the following are divisible by 81: 81 = 1 x 81 162 = 2 x 81 243 = 3 x 81 324 = 4 x 81 and so on. ========================================= Did you mean to ask "What is 81 divisible by?" 81 is divisible by 1, 3, 9, 27, 81.
Yes, 486 / 6 = 81
324/4 = 81 ( a whole number )
81 and 162 are both multiples of 3. In mathematics, a number that can be divided by another number without leaving a remainder is said to be divisible by that number. Both 81 and 162 can be evenly divided by 3, making them multiples of 3.
The divisibility test for the number 9 is: Any number whose digits add up to 9 or a multiple of 9, is divisible by 9. Any other number the sum of whose digits do not add up to 9 or a multiple of 9, are not divisible by 9.For example, the digits of 81 sum up to 9, and therefore, 81 is divisible by 9. The digits of the number 319381482 add up to 39, and therefore, 319381482 is divisible by 9.
Any multiple of 81.
It has more than two distinct factors; they are 1, 3, 9, 27, 81
