Question

Мила и Женя придумали по числу и выписали на доску все натуральные делители своих чисел. Мила написала 10 чисел, а Женя 9 чисел, а максимальное число, написанное на доске дважды, равно 50 Сколько всего различных чисел выписано на доске?

Answer 1

Всего выписано 19 чисел
Т.к. 50=2·5², то  одинаковыми будут делители 1, 2, 5,10, 25, 50
19-2·6=7
7+6=13
Ответ выписано 13 различных чисел

Answer 2

Problem Analysis

Mila and Zhenya wrote down all the natural divisors of their respective numbers on the board. Mila wrote down 10 numbers, while Zhenya wrote down 9 numbers. The maximum number written on the board twice is 50. We need to determine the total number of different numbers written on the board.

Solution

To find the total number of different numbers written on the board, we need to consider the divisors written by both Mila and Zhenya. Let's analyze the given information step by step:

1. Mila wrote down 10 numbers. 2. Zhenya wrote down 9 numbers. 3. The maximum number written on the board twice is 50.

To solve this problem, we need to find the divisors of the numbers written by Mila and Zhenya. However, the specific numbers written by Mila and Zhenya are not provided in the question. Therefore, we cannot determine the exact divisors without additional information.

Please provide the specific numbers written by Mila and Zhenya so that we can calculate the total number of different numbers written on the board.
