WebHow to Quickly Calculate the GCD in E (Bonus) and A. Bonus of E: The only algorithm costing ω ( s n) in the official solution is calculating GCD. However, we can calculate gcd ( x, s n) for all x ∈ [ 1, s n] in Θ ( s n): since ∀ x, y ∈ Z satisfying gcd ( x, y) = 1 , g c d ( x y, s n) = g c d ( x, s n) ⋅ g c d ( y, s n) (this property ... WebThe first line of each test case contains the integers n and k ( 1 ≤ n ≤ 2 ⋅ 10 5, 1 ≤ k ≤ n) — the length of the array a and the minimum amount of times each number in the range [ l, r] should appear respectively. Then a single line follows, containing n integers describing the array a ( 1 ≤ a i ≤ 10 9 ). It is guaranteed that ...

WebSince a2=gcd (b2,b3), both b2 and b3 has to be divisible by a2 Similarly both b3 and b4 has to be divisible by a3 So the common element which has to be divisible by both a2 and a3 is b3 That's why b3=lcm (a2,a3) Now that you have b3 just check if gcd (b2,b3) is equal to a2 or not. If it is not then answer is "no".
