/*Amazon(level-easy)

Given a number n, the task is to find the even factor sum of a number.
INPUT : The first line consists of an integer T i.e. the number of test cases. First and last line of each test case consists of an integer n.
OUTPUT : Print the sum of even factors of the given integer n.

CONSTRAINTS :
1<=T<=100
1<=n<=105

EXAMPLES:
INPUT :
2
30
18

OUTPUT : 
48
26
