Did you mean prime factor?

২ টাই বের করলে ভাল হয়। ২ টার ই সল্যুশান পাইয়া যাবো।
তবে এইটা একটা প্রশ্নে পাইছি। Chittagong math club এর একটা প্রশ্ন আমি পেয়েছি। ওখানের প্রশ্ন থেকে শুধু কপি কইরা পেস্ট মারছি ।

মানে $34^{122}+34^{123}+34^{124}$ নিজেই তো এইটার সবচেয়ে বড় উৎপাদক (factor), তাইনা? তাহলে আর বের করার দরকার কি?

Largest prime factor 397
$34^{122}+34^{123}+34^{124}=34^{122}(1+34+34^2)=17^{122}\cdot 2^{122}\cdot 3\cdot 397$
