The program should direct the user to input two numbers: MIN and MAX (MIN is guaranteed to be not larger than MAX). Starting with the number MIN and ending with the number MAX, in descending order, create an output line listing its prime factors in ascending order. Skip factorization for the prime numbers if they are within this bracket.
Below is an example of the output for MIN = 7 and MAX = 10.
8=2*2*2
9=3*3
10=2*5
MIN = MAX is a valid input that will result in a single line as output (or no output). You should not pre-populate your program with a table of prime factors.
Additional consideration. TextBox is a strong candidate for directing and accumulating the output. Its advantage over Label is availability of sliders, so there is no limit to how many lines of output can fit in it.
