The first question is:
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

The answer is E. 72=3*24; LCM of 4,6 and 8

Can anybody explain why I can solve this problem by calculating the LCM of 4, 6 and 8?
