Sorry it's a bit messy. but I hope you understand and it will help
132/2 = 66
66/2 = 33
33/3 = 11
11/11 = 1
132 = 2^2 * 3 * 11
55121/11 = 5011
5011/5011 = 1
55,121 = 11 * 5011
LCM = common factor with larger exponent * not common factors
LCM = 2^2 * 3 * 11 * 5011
LCM = 661,452
The question is asking which of the following does not have side that are parallel. So which of them have lines that would never touch if they were never ending lines.
This is what WolframAlpha says. Look at the image below.
