Thank you for the opportunity to help you with your question!
i will help you. you see, prime factorization deals with getting numbers divisible by a bigger number. as from your question, what you have are the factors and what you should actually look for is the original number since what you have are the factors of that number. it will be
2730 + 1.
Hope this did assist. Please let me know if you need any clarification. I'm always happy to answer your questions. I will be pleased if you make me your private tutor.
