There are 15 members in a chorus. How can we notify each member as quickly as possible by calling one person every minute? How can we notify 50 members?

Is it 15 people to notify 50 people?

15 people call to notify 15 people and let the 15 people notified notify the other 15 people after 1 minute (tell them which 15 people to notify)

The 15 people in the chorus also notify 15 people at the same time (do not overlap), leaving 5 people who have not been notified, and the notification will be completed in one minute
