Check out a one-way ANOVA for this kind of problem. Do the calculations to find the F-ratio to compare to the critical or cutoff value from the F-distribution table (used for ANOVA tests). Find the critical or cutoff value at .05 level of significance using the table to reject the null hypothesis (which would state that all population means are equal). If the null is rejected in favor of the alternate hypothesis (which would state that all population means are not equal), then you can conclude a difference.

One of the most common post hoc tests include Tukey's HSD test. There may be others you can use as well.
