You have a Tree T with N nodes where each node has a value A₁ It is given that the cost of the tree is the LCM of all values of the tree nodes. Find the minimum size of a subgraph of the tree such that its cost is equal to the cost of T. Notes: kumar15228 Kumar15238 • A subgraph of a tree is a tree formed by erasing some nodes of the tree with their edges such that the remaining graph is connected. kumar15 • It's guaranteed that the LCM of the values of all nodes does not exceed 10⁹. 15238
