Yowza! I had thought that using FACTORS would be faster than using FACTOR because the former is faster... but that's not the only factor here (as it were). Good job! Smile

Yep. Timing for input of 12345678:

John: 0.177_s

Gerald's shines even brighter on things like large factorials. Try 20! to see what I mean.
