The number of party favors is common divisor(180;396)
But we must find the greatest number of party favors ⇒the greatest number of party favors is most grand common divisor(180;396)
We have: 180=2^2·3^2·5
396=2^2·3^2·11
⇒most grand common divisor(180;396)=2^2·3^2=36
⇒the greatest number of party favors Amy can make is 36
good luck
