Answer:
i think its 20
Explanation:
Primer of 10: The prime factorization of 10 is 2 * 5. The sum of its distinct prime factors is 2 + 5 = 7.
Now, let's calculate the primer for each of the other numbers:
Primer of 12: The prime factorization of 12 is 2 * 2 * 3. The sum of its distinct prime factors is 2 + 3 = 5.
Primer of 14: The prime factorization of 14 is 2 * 7. The sum of its distinct prime factors is 2 + 7 = 9.
Primer of 20: The prime factorization of 20 is 2 * 2 * 5. The sum of its distinct prime factors is 2 + 5 = 7.
Primer of 30: The prime factorization of 30 is 2 * 3 * 5. The sum of its distinct prime factors is 2 + 3 + 5 = 10.
The only one that is same as primer of 10 is 20! :)
