How many 3 digit numbers have even no of factors?
878 three digit numbers have an even number of factors. Every factor of a number has a pair, so there ought to be an even number of factors for every number. However, if a pair of the factors are the same number, then there will be an odd number of factors, that is if the number is a perfect square. Assuming three digit numbers are 100 to 999: From 100 to 999, the perfect squares are 102 = 100 to 312 = 961, a total of 31-10+1 = 22 numbers. So of the 999-100+1 = 900 three digit numbers, 22 have an odd number of factors, so 900-22 = 878 have an even number of factors.

Whats the maximum number of zeros in a number?
The maximum number of zeros in a number is determined by the number of factors of 10 in that number. Each factor of 10 is made up of 2 factors of 5 and 2 factors of 2. Therefore, the maximum number of zeros in a number is equal to the minimum of the number of factors of 5 and the number of factors of 2. For example, in the number 1000, there are three factors of 10, so the maximum number of zeros is 3.
