A teacher gave a task to two of his students. He wrote some prime numbers on the blackboard. He asked one of his students, Ajay, to form all possible triplets among them. He then asked him to find the product of the numbers in each triplet. He asked another student, Anand, to find the GCD of every pair of products found by Anand. Both followed the teachers instructions. Anand found that exactly 315 of the GCDs were prime. How many numbers did the teacher write on the blackboard?
Please share your approach also!
