This is a REST API backend that, given a number, serves the factors of that number. It is written in Java and uses the Spring Boot library.
Run the application using Maven by running:
./mvnw spring-boot:run
The default port is set to 8080. The format for accessing the factors of a number are as follows:
http://{website}:8080/api/{number}/factors
The webserver currently does not support HTTPS, so not specifying the port may give you an SSL error depending on the browser you use.
