J C is right. The number is 10!, which is the product of all the integers from 1 through 10. So no matter which of the integers from 1 to 10 you divide by, the quotient is always the product of the remaining integers in that interval.

Easy. 10 factorial = 3628800
divide out the extra 5, 9 and 32 to get the smallest one = 2520

It must be 5 x 7 x 8 x 9 = 2520
Any multiple of 2520 will do.
