Math - Sewing question

Question

Lee is sewing vests using 16 green buttons and 40 blue buttons. All the vests are identical, and all have both green and blue buttons. What are the possible numbers of vests Lee can make? What is the greatest number of vests Lee can make?

Answer 1

Lee can make up to 16 with one green button.

Lee can make up to 8 with 2 green buttons.

Lee can make up to 4 with 4 green buttons.

Lee can make up to 2 with 8 green buttons.

Lee can make 1 vest with 16 buttons.

Now, if the problem said all the buttons have to be used, the most Lee can make is 8 (2 greens and 5 blues) because 16 does not divide evenly into 40.
