39. Students are cleaning a local park in groups. There are 50 boys & 75 girls. Each group has the same number of boys and the same number of girls. What is the greatest possible number of groups?

40. You are dividing a community garden 35 m long by 15 m wide into equal sized square gardens. Find the greatest possible dimensions of each square.

Sorry, I'm just having some trouble understanding these kinds of problems :) I have three more like these after that, but I figured that if I could get some help on these then I would understand the others. Thanks. :D

Find the lowest common factor (besides just 1) of 50 and 75: 5

So, if each group has 5 boys or girls, you have 10 groups of boys and 15 groups of girls

The GCD of 15 and 35 is 5
So, make 5x5 squares. 3x7 of them.
