160 = 2 x 2 x 2 x 2 x 2 x 5 = 2^5 x 5
160 = 25 x 5, 432 = 24 x 33. LCM = 25 x 33 x 5 = 4320
32 times 5 equals 160
To find the original number, we can set up the equation: (5/8)x = 100. To solve for x, we can multiply both sides by the reciprocal of 5/8, which is 8/5. This gives us x = 100 * (8/5) = 160. Therefore, the original number is 160.
These: 1 x 160, 2 x 80, 4 x 40, 5 x 32, 8 x 20, 10 x 16
