Задача 39223. Integer Divisors


Задача

Темы: ЕГЭ
Let M – the sum of 5 of the maximum non-trivial divisors of an integer (not counting one and the number itself). If the number does not have 5 non-trivial divisors, then the M value is considered equal to zero.
Write a program that iterates over the integers less than 20 000 000, in descending order and finds among them the first 5 for which the value 0 < M < 10 000 000 and in M there is only one  even digit.

Print the first five found numbers and their corresponding values ​​M

Output format: for each of the five such found numbers in a separate line, the number itself is displayed first, then – value M (separated by one space). Lines are displayed in descending order of found numbers.
