Answer 1

Делители 30: 1, 2, 3, 5, 6, 10, 15, 30
значит: 2, 6, 10

Answer 2

На 30 делится 2,6,10.

Answer 3

To find the numbers from the given list that have 30 divisors, we need to identify the numbers that have exactly 30 positive divisors.

A positive integer n has 30 divisors if it can be expressed in the form n = p^2 * q^4, where p and q are distinct prime numbers. The exponents (2 and 4 in this case) indicate the number of divisors for each prime factor.

Let's check each number from the given list to see if it satisfies this condition:

1. 2 = 2^1 * 1^4, but it has only two divisors (1 and 2).
2. 4 = 2^2 * 1^4, but it has only three divisors (1, 2, and 4).
3. 6 = 2^1 * 3^1, but it has only four divisors (1, 2, 3, and 6).
4. 8 = 2^3 * 1^4, but it has only four divisors (1, 2, 4, and 8).
5. 10 = 2^1 * 5^1, but it has only four divisors (1, 2, 5, and 10).
6. 12 = 2^2 * 3^1, but it has only six divisors (1, 2, 3, 4, 6, and 12).
7. 16 = 2^4 * 1^4, but it has only five divisors (1, 2, 4, 8, and 16).
8. 18 = 2^1 * 3^2, but it has only six divisors (1, 2, 3, 6, 9, and 18).

None of the numbers in the given list have exactly 30 divisors based on the given condition.
