All I did was make a factor tree. The GCF (Greatest Common Factor) is 5. :)
35 5,7
7,5
35 5,7
35 5,7 Not much of a tree. More like a factor shrub.
35 5,7
35 5,7 No exponents required.
63 3,21 3,3,7 35 5,7
It's 35
(140) = 2 * (70) (70) = 2 * (35) (35) = 5 * 7 Prime factors of 140: 2,2,5 and 7
Pretty small. 35 5,7
The factor tree is as follows: 114 57,2 19,3,2
