Note that

  • 30=2·3·5;
  • 42=2·3·7.

Find the grearest common factor GCF(30,42). You can see that numbers 30 and 42 have common factors 2 and 3, then

[tex]GCF(30,42)=2\cdot 3=6.[/tex]

This gives that the greatest number of identical vases florist can fill is 6. Each vase will contain

  • [tex]30:6=5[/tex] carnations;
  • [tex]42:6=7[/tex] roses.

Therefore, in each vase will be 12 flowers (5 carnations and 7 roses).
