## Description

When you look at a number, you may be concerned about whether it is a prime number. At that time, you can quickly investigate with this app.<br>When you enter a number and start a survey, it calculates and displays all divisors of that number to determine if it is a prime number. The found prime numbers are recorded in the local area and can be checked at any time.<br>In addition, as a bonus function, you can perform a benchmark test to measure the calculation speed of the smartphone by performing calculations to find all prime numbers less than 100,000.<br><br>The benchmark result posting bulletin board has been set up on my homepage &quot;Mobile Programming Network&quot;, so please post it!<br>
