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 945 what is the least possible value of k?	Choose the most appropriate option:
A) 5  B) 7  C) 9  D) 11  E) 13
945 = 3*3*3*5*7   Thus k must include numbers at least up to the number 9 so that there are at least three appearances of 3 (that is: 3, 6, and 9).   The answer is 9.
