Factorial de un entero no negativo, es la multiplicación de todos los enteros positivos menores o iguales a n. Por ejemplo, el factorial de 6 es 6*5*4*3*2*1, que es 720.
Un factorial está representado por un número y un ” ! marca ” al final. Es ampliamente utilizado en permutaciones y combinaciones para calcular los posibles resultados totales. Un matemático francés, Christian Kramp, utilizó por primera vez la exclamación.
