ten 2 / 9 x 45 = 2 / 9 x 45 / 1 = 2 x 45 / 9 x 1 = 90 / 9 = 10 / 1
2 x 2 x 2 x 2 x 2 = 32 3 x 3 x 5 = 45
2 x 2 x 45 = 180
45 = 3 x 3 x 5 56 = 2 x 2 x 2 x 7
GCF(45, 90) = 45 and so 45 + 90 = 45*(1 + 2).
1 x 45 = 45 2 x 45 = 90 3 x 45 = 135 4 x 45 = 180 5 x 45 = 225 6 x 45 = 270 7 x 45 = 315 8 x 45 = 360 9 x 45 = 405 10 x 45 = 450 11 x 45 = 495 12 x 45 = 540
2 x 2 x 2 x 3 x 3 x 5 = 360
1. (28 = 2 x 2 x 7, 45 = 3 x 3 x 5)
The prime factors are: 2 x 2 x 2 x 3 x 5
The volume will by x * x * 2 = 2x^2 cubic units.
The GCF of 36, 40, and 45 is 1. Add: 36 = 2 x 2 x 3 x 3 40 = 2 x 2 x 2 x 5 45 = 3 x 3 x 5 GCF = 1
3 x 3 x 5 = 45 2 x 2 x 3 x 3 = 36
