Patton is organizing his stamp collection into ab ook. He has 42 foreign stamps and 70 US stamps. He wants every page to have the same number of foreign stamps and the same number of US stamps. If he puts the greatest number of stamps on each page, how many pages will he use?
I thought the answer was 8. Because the GCM is 14 and for 42 stamps it would be 3 pages and for 70 stamps it would be 5 pages, so 5+3=8
21 foreign and 35 US stamps on each page.
