For any integer k greater than 1, the symbol k* denotes the product of all integers between 1 and k, inclusive. If k* is a multiple of 525 what is the least possible value of k?
Pick one.
A) 10	B) 14	C) 15	D) 21	E) 25
525 = 3*5*5*7   Thus k must include numbers at least up to the number 10 so that there are two appearances of 5.   The answer is 10.
