Hola Snark.
Hace un tiempo se propuso un problema en los desafíos matemáticos de el
país.
Yo lo he modificado un poco y queda así:
Encontrar todos los números enteros que podemos separarlos en dos partes x
e y de forma que al multiplicar 7*x*y obtengamos el número inicial (el que
sale al escribir x seguido de y)
Hay muchísimas soluciones pero siguen un patrón determinado.
Un saludo

P.D. Para operar con números muy grandes podéis utilizar esta calculadora
