Prime Number Finder

Range is quite low, < 100000000.

Works well and very useful for students especially....:)

I have prime number synesthesia (related to ordinal linguistic personification) where prime numbers feel smooth and composite numbers feel rough, and it's really irritating when a number feels both borderline rough and smooth. This app helps relieve my anxiety and firmly helps me place that number in the rough versus smooth category!

This app is very useful in math test or homework

Greatt.. realy fantastic.. very fast..

This app is the best ever app I have ever saw. This is also much helpful app then others for separating the numbers into prime or composite

If the feature of number of factors is added then it would be appreciated

Amazing , Really helps in Number theory

Simple to use

Easy to find out

Helps find all of the factors of radicals to find the largest perfect square.

This is a good app because it tells you if a number if prime or composite, so if you need it for that, it's great. It's also great because it tells you all of the factors of that number, so if you ever needed to know the factors of a number for homework, simplifying equations/expressions, or anything else, it would be useful.
