Problems on numbers

Number theory is one of the most appealing topics in mathematics. Given one or more numeric values, a numeric algorithm performs some computation. The use of number theory in computing is important for applications like in the case of cryptographic algorithms. Number theory is also used in various applications such as calculating hash functions or in information security. Euclid’s algorithm is one of the oldest number-theoretic algorithms which is used to calculate the greatest common divisor of two numbers.

Correct answer will be upvoted else downvoted. Computer science. positive integer is the gcd of that integer with its amount of digits. Officially, gcdSum(x)=gcd(x, amount of digits of x) for a positive integer x. gcd(a,b) means the best normal divisor of an and b — the biggest integer d to such an extent that the two integers an and b are detachable by d. For instance: gcdSum(762)=gcd(762,7+6+2)=gcd(762,15)=3. Given an integer n, track down the littlest integer x≥n to such an extent that gcdSum(x)>1. Input The primary line of input contains one integer t (1≤t≤104) — the number of experiments. Then, at that point, t lines follow, each containing a solitary integer n (1≤n≤1018). All experiments in a single test are unique. Output Output t lines, where the I-th line is a solitary integer containing the response to the I-th experiment.
Solve the following question
Let n E N be a natural number with a divisor d E N. If the sum of all of the positive divisors of n is equal to 2n + d, then we call n a near- perfect number. For example, if we have n = 12, then the divisors of n are 1, 2, 3, 4, 6 and 12. Therefore, the sum of the divisors of n is equal to 1+2+3+4+6+12=2*12+4, and 4|12. Hence, 12 is a near-perfect number. Write a function, near_perfect_number, which accepts any integer n as input, and returns True if n is a near-perfect number, and False otherwise.
