What is the smallest number that should be added to 100 so that it can be completely divided by all the prime numbers between 10 to 15 ?

What is the smallest number that should be added to 100 so that it can be completely divided by all the prime numbers between 10 to 15 ? Correct Answer 43

আমরা জানি, 10 থেকে 15 এর মধ্যে অবস্থিত মৌলিক সংখ্যাগুলো হলো 11 এবং 13। এখন 11 এবং 13 এর ল. সা. গু. হলো 143 । সুতরাং (143 – 100) = 43 । ∴ 100 এর সাথে কমপক্ষে 43 যোগ করলে তা11 এবং13 দ্বারা বিভাজ্য হবে।
