    Tsao, Hung-ping (2022). Evolutionary mathematics and science for On the Terminal Value Distribution in the Process of Successively Summing up all Prime Factors of a Given Natural Number. In: "Evolutionary Progress in Science, Technology, Engineering, Arts, and Mathematics (STEAM)", Wang, Lawrence K. and Tsao, Hung-ping (editors). Volume 4, Number 8D, August 2022; 40 pages.

One is 142857 found in the pyramids of ancient Egypt, the other 2982868385 found in my recent research of triangular arrays. It is known that each natural number greater than 1 can be expressed as a unique product of prime numbers, namely the prime factorization. For example, 84=2×2×3×7. By summing up all prime factors of 84, we obtain 2+2+3+7=14. Since 14=2×7, we further sum up all prime factors of 14 to obtain 2+7=9. Since 9=3×3 and 3+3=6, we can continue the same process to finally come up with 6=2×3 and 2+3=5, which is a prime number. Accordingly, we obtain 5 to be the terminal value of 84. Using the above process of successively summing all prime factors of a given natural number, I tried to make my decision as to which of 142857 and 2982868385 is the most wonderful based on their terminal values: whichever is less is the most wonderful. I’ll let you find it out. Meanwhile, I am making the following conjecture. Conjecture: Withing a certain limit, the probability of 5 being the terminal number is about the same as the probability of 7, 11 or 13 being the terminal number, which is approximately equal to 0.3.
    Notes:
    Conjecture: Withing a certain limit, the probability of 5 being the terminal number is about the same as the probability of 7, 11 or 13 being the terminal number, which is approximately equal to 0.3.
