WebHang on, is the question how many 0's are at the end of 30! or how many zero's are there in 30! (i.e. when written out in full in base 10?) Because the answer to the first question has been answered several times already in this thread. The answer to the second one is tricky unless you write 30! in full and I don't know any other way to figure out the answer... WebTo start with, the number of trailing zeroes in the decimal representation of a number = highest power of 10 that can divide the number. For instance, 3600 = 36 * 10 2 45000 = 45 * 10 3 In order to approach this question, let us first see the smallest factorial that ends in a zero. 1! = 1 2! = 2 3! = 6 4! = 24 5! = 120

WebA problem involving factorials and factorization, implicitly using the Fundamental Theorem of Arithmetic Web10 aug. 2012 · Then there must be a zero. Then there are 10 possibilities for the last digit. This gives 12 * 10 = 120 numbers containing a 0 at the third digit. The solution for the range (1 to 1234) is therefore: ?0??: 1 * 100 = 100 ??0?: 12 * 10 = 120 ???0: 123 Total = 343 But an exception is if n contains a zero digit. Consider the following case: x <= 12034. incpa society
