素数調査ましーん

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.
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.
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.

The benchmark result posting bulletin board has been set up on my homepage "Mobile Programming Network", so please post it!
