一个 150X324X375 的长方体

是由 1X1X1 的单位立方体胶合在一起而成，问这个长方体的一条对角线穿过多少个单位立方体的内部？

150 + 324 + 375 - GCF(150,324) - GCF(150,375) - GCF(324,375) + GCF(150,324,375) = 768? Tried some small numbers and then guessed

Your problems are too big bones to me!

Except the Erdos problem (I could not solve it either ), they are no more difficult than the problems you solved before (at WXC and here). I am posting another problem. If you dont solve it, I will conclude that you just dont want to do my problems.

你好厉害呀，比我导师还逼得厉害！为了不被说成“just dont want to do my problems”，周末一早就来做功课 . I saw this problem has been solved in WXC, (I went there not on purpose, as you guys talked about posting my problems on WXC), I still post my answer here to let you know at least I have tried.
