Write a function that returns the least common factor of two integers. For example, if the integers were 24 and 32 the function would return 2. The test suite is provided in the file below, but add further tests to ensure your function works. Add statements to the main program in the test program provided that prompt the user to enter two integers, the numerator and denominator of a fraction and reduce that fraction to its lowest form. For example, if the user enters 8 and 36 the program would print 2 and 9. (Of course, the normal way to simplify a fraction is to find the greatest common factor, not the least as we do here.) Make sure your program works for improper fractions and fractions in which either or both numerator and denominator are negative.
