say a,b,c,d are the consecutive numbers. Among them,

there are two even numbers definetly. by the same reasoning,

there is at least one number divisible by 3 and

there is exactly one number divisible by 4.

thus, numbers 2,3 and 4 have their representatives (multiples) contributing to the product.

hence 2*3*4=24 should divide a*b*c*d - September 8th 2009, 12:12 AMguruthanks
