Answers to Questions

How to calculate a primorial?

The term primorial refers to two separate definitions:

Primorial defined as the product of all prime numbers inferior or equal to n is a simple multiplicationhref conditioned par a primality test of the numbers inferior or equal to n.

1, 2, 6, 6, 30, 30, 210, 210, 210, 210, 2310, ...

Primorial defined as a product of the n first primes is equivalent to a multiplicationhref of the list of the first n primes :

2, 6, 30, 210, 2310, 30030, 510510, ...

In both cases, the primorial of p is written with the character sharp: p#
