# * Example 1:
# * Find all the common factors of 12 and 18.
# * Factors of 12 are 12, 6, 4, 3, 2, 1
# * Factors of 18 are 18, 9, 6, 3, 2, 1

# Using the Python language, have the function IntersectingLines(strArr)
# take strArr which will be an array of 4 coordinates in the form: (x,y).
# Your program should take these points where the first 2 form a line and
# the last 2 form a line, and determine whether the lines intersect, and if
# they do, at what point.
# For example: if strArr is ["(3,0)","(1,4)","(0,-3)","(2,3)"], then the line
# created by (3,0) and (1,4) and the line created by (0,-3) (2,3)
# intersect at (9/5,12/5). Your output should therefore be the 2 points in
# fraction form in the following format: (9/5,12/5). If there is no denominator
# for the resulting points, then the output should just be the integers like so: (12,3).
