Find the value for lcm $$[5,7,11]$$. 
Overseas Competition->Knowledge Point->Number Theory Modules->Factors and Multiples->Common Factors and Common Multiples
Since $$5=1\times5$$, $$7=1\times7$$, and $$11=1\times11$$, we have one $$5$$, one $$7$$, and one $$11$$, thus the least common multiple for $$5$$, $$7$$, and $$11$$ is $$5\times7\times11=385$$. We choose $$\rm A$$．
