# Weekly Problem 45 - 2009

##### Stage: 2 and 3 Short Challenge Level:
The number of bunches must divide the number of white roses, the number of yellow roses and the number of red roses. The highest common factor of $24$, $36$ and $42$ is $6$, so the most bunches Flora can make is $6$, each consisting of $4$ white, $6$ yellow and $7$ red roses.

This problem is taken from the UKMT Mathematical Challenges.
