The Distribution of Prime and Composite Numbers by its Unit Digit

Dagnachew Jenber


This paper studies the nature of prime and composite numbers that the way they distribute using their unit digits. Specifically, it studies the nature of numbers with unit digit 1, 3, 7 and 9 only. There are polynomial sequence functions associated with numbers with unit digit 1, 3, 7 and 9. I hope programmers will use these sequence functions to code an algorithm which is much more important than the previous algorithms to determine the factor of particular composite numbers as well as tracking new prime numbers with in short period of computers time.
