Natural-VPAM (Visually Perfect Algebraic Method)
Two calculators :
The second one is Solar.
fx-82 AU Plus : light fx-83GT plus for australian market.
fx-86 DE Plus : same as fx-85GT plus for german market.
Prime factor factorization : FACT function.
Only prime factors
Example #1 : for 11803, the function returns 11 X 29 X 37.
Example #2 : for 9876487651, the function returns 577 X (17116963)
For p, The algorithm tests all numbers
For 2018, the function returns 2 X (1009), It can not find that 1009 is a prime factor allthough all divisors should be less then 1000 and one of then less than its square root (45)....
