How can I get this R code to pass the "1 minute" test for this Project Euler question?
You should change the algorithm in order to make your program run faster. The while loop is performed over 200 million times (printing out information in every iteration) until it reaches the desired number.

If you calculate the answer using LCM (taking the least common multiple of all numbers between 1 and 20), the program should run instantly in pretty much any programming language.
