Abstract
If factorials enter into product-quotient expressions, not allowing approximative calculation, the factorization into powers of primes is recommended. The paper describes a computer program for this process, based on a known formula, which should be applied differently, according as the primes are large or small. A discussion shows how to distinguish between large and small in order to minimize the computing time.
