Go into the code and click the 2 lines on the bottom right This is unique because the GCF and LCM let you directly input a list and also it supports decimals
This has 3 custom blocks Factors(n) - gives you the factors of the number(outputs to t1 list) LCM(a list) - gives you the lcm of given list(it also supports decimals) and it is very optimized - outputs to result variable GCF(a list) - same thing as lcm but gives gcf instead
