Determine whether or not each number is a common factor of 144 and 240. try to use different methods, and show your work. a) 2 b) 3 c) 10 d) 48 e) 120

Step-by-step explanation:

2| 144

2|  72

144=2×2×2×2×3×3

2 | 240

2 | 120

2  | 60

2  | 30

3  | 15

   |  5

240=2×2×2×2×3×5

greatest common factor=2×2×2×2×3=48

a. 2 divides both ,so common factor

b. 3 divides both ,so common factor
