"Prime factorization" has become a game!
Let's challenge the limits of prime factorization!
Easy to use!
Just factorize the displayed number and enter the formula!
If the answer is correct, points for that number are added, and if the answer is incorrect, points are subtracted.
A difficulty selection function has been added!
For those who are still new to prime factorization, try "Normal mode", and for those who are serious about factoring, try "Hard mode" and try to solve a lot of prime factors!
In normal mode, the time limit is 40 seconds,
Hard mode has a time limit of 90 seconds!
How well can you factorize prime factors?
