## Description
|
|||
|
|
<section id="description"> n，rad（n）的基数是n的不同素因子的乘积。例如，504 = 23×32×7，因此rad（504）= 2×3×7 = 42.如果出现以下情况，我们将正整数（a，b，c）的三元组定义为abc-hit：GCD（ a，b）= GCD（a，c）= GCD（b，c）= 1 a <ba + b = c rad（abc）<c例如，（5,27,32）是abc-hit，因为：GCD（5,27）= GCD（5,32）= GCD（27,32）= 1 5 <27 5 + 27 = 32 rad（4320）= 30 <32事实证明abc-hits是非常罕见的c <1000只有31次abc命中，Σc= 12523。查找Σc表示c <120000。 </section>
