Penny and Jacob were at the library. Penny’s favorites number was 50, and Jacob’s favorite number was 10. So they both wanted to get a GCF of there favorite number of books to put in their bookbag. How many books can they put in their bookbag?
Hmmm well our favorite numbers are both whole numbers so maybe the answer could also be a whole number.
Let's list all the factor's of our favorite numbers.
For 50 the factors are... 1, 2, 5, 10,25, 50
For 10 the factors are... 1, 2, 5, 10
So our GCF is 10!!! we can fit 10 books in each book bag.
