Description: Up to a few issues about some positive integer x can be divisible by x number of positive integer. Some positive integer x the number recorded as the number of div (x). For example, 1,2,5,10 are about 10 positive integer number, and div (10) = 4. For a and b are two positive integers, a ≤ b, find a and b between the number of up to about a few of the number of x. Programming tasks: For a given two positive integers a ≤ b, calculated between a and b about the number of the largest number of number. Input input data line 1 are two positive integers a and b.
