Here's the question:
A wire is cut into three equal parts. The resulting segments are then cut into 4, 6 and 8 equal parts respectively. If each of the resulting segments has an integer length, what is the minimum length of the wire?
a) 24
b) 36
c) 48
d) 54
e) 72
I would think (4+6+8) * 3= 54 would be the correct answer.
But you have to take the LCM of 4,6,8 and you would get 24, and then you would multiply 24 *3= 72. Why would you do the LCM? I have a hard time visualizing this.
