The number of students who attend a school could be divided among 10, 12, or 16 buses, such that

each bus transports an equal number of students. What is the minimum number of students that

could attend the school?

(A) 120

(B) 160

© 240

(D) 320

(E) 480

hello, I am unable to find the answer to this with the formula lcm = P*Q/GCF. Can someone tell why?
