Problem Statement

The sequence of natural numbers is based on the following rule: each term, starting with the second, is obtained from the previous addition works of all its various simple divisors (for example, after the number 1212 should be the number 1818, and after the number 125125 , the number 130130). Prove that any two sequences constructed in this way have a common member.
