( 9424 ) D X-Magic Pair PROGRAMMING math number theory

B'You are given a pair of integers (a, b) and an integer x . You can change the pair in two different ways: The pair (a, b) is called x -magic if x is obtainable either as a or as b using only the given operations (i.e. the pair (a, b) is x -magic if a = x or b = x after some number of operations applied). You can apply the operations any number of times (even zero). Your task is to find out if the pair (a, b) is x -magic or not. You have to answer t independent test cases. The first line of the input contains one integer t ( 1 <= t <= 10^4 ) -- the number of test cases. The next t lines describe test cases. The only line of the test case contains three integers a , b and x ( 1 <= a, b, x <= 10^{18} ). For the i -th test case, print YES if the corresponding pair (a, b) is x -magic and NO otherwise. '...
