4. How can these relate to math?

5. We can use them to find the GCF!
Find the GCF of 30 and 65.
Draw two circles that overlap
Label each circle factors of 30 and factors of 65
Write out the factors of 30 inside the proper circle
Write out the factors of 65 inside the proper circle
Write out the factors that both
numbers have in common
in the overlapping
part of the circles
The largest number in
the overlapping circle
is the GCF!!
Factors of 65
Factors of 30 5 1 2 1 5 3 13 15 6 10 30 65

6. In your groups, complete a Venn diagram on a colored sheet of paper for 4 of the following!
Find the GCF of 32 and 48.
Find the GCF of 54 and 72.
Find the GCF of 36 and 144.
Find the GCF of 24, 32 and 64.
Find the GCF of 35, 49, and 84.
Find the GCF of 28, 56, and 84.
