3378. Count Connected Components in LCM Graph

LeetCodeArrayHash TableMathUnion-FindNumber TheoryOpen on judge ↗

You are given an array of integers nums of size n and a positive integer threshold. There is a graph consisting of n nodes with the ith node having a value of nums[i]. Two nodes i and j in the graph are connected via an undirected edge if lcm(nums[i], nums[j]) <= threshold. Return the number of connected components in this graph. A connected component is a subgraph of a graph in which there exi
