This simple algorithm incomplete can only calculate prime numbers?
Ciao,
3 x 3 x 2 x 4 = 72 1 = 71 (is a prime number)
now 5:
3 x 3 x 2 x 4 x 3 x 2 x 3 x 4 x 5 = 25920 1 = 25919 (is a prime number)
.
now 6 :
3 x 3 x 2 x 4 x 3 x 2 x 3 x 4 x 5 x 3 x 2 x 4 x 3 x 4 x 5 x 6 = 223948800 1 = 223948799 ( is a prime number)
ho isolato il
2 x 4
now 7 :
3 x 3 x 2 x 4 x 3 x 2 x 3 x 4 x 5 x 3 x 2 x 4 x 3 x 4 x 5 x 6 x 3 x 4 x 5 x 3 x 4 x 5 x 6 x 3 x 5 x 6 x 7 = 3047495270400000 1 = 3047495270399999 ( is a prime number)
Do you understand the mechanism? then work to the 8 910 ........ should be all primes larger.
