56 = 2 x 2 x 2 x 7 = 2^3 x 7
64 = 2 x 2 x 2 x 2 x 2 x 2 = 2^6
48 = 2 x 2 x 2 x 2 x 3 = 2^4 x 3
72 = 2 x 2 x 2 x 3 x 3 = 2^3 x 3^2
120 = 2 x 2 x 2 x 3 x 5 = 2^3 x 3 x 5
64 = 2 x 2 x 2 x 2 x 2 x 2 = 2^6
48 = 2 x 2 x 2 x 2 x 3 = 2^4 x 3
72 = 2 x 2 x 2 x 3 x 3 = 2^3 x 3^2
120 = 2 x 2 x 2 x 3 x 5 = 2^3 x 3 x 5
