Ahh, of course that explains it then. It’s only a totient number rather than Harshad number (no wonder I dropped advanced maths for Economics and Accg in year 12 haha)I’m no mathematician but looked up properties of 119 and was misled. You’re right it isn’t a Harshad number like 117 (1+1+7=9) and 120 (1+2+0=2).
119 is apparently a totient number but the explanation for that is above my pay grade.
