No number has the multiples of 1, 2, 4, 5, 8, 10, 16, 20, 40, 80, but the number 80 (and all its multiples: 160, 240, 320, 400, ...) has them all as FACTORS.
8 x 320 = 2560
54,108,162,216,270 or probably 108,162,216,270 and 320
40 x 8=320
64, 128, 192, 256, 320, 384, 448, 512, 576, 640 are the first ten multiples of 64.1,2,4,6,8,32,64 are the factors of 64, not the multiples.
320, 640, 960, 1280, 1600, 1920 and so on.
320, 640, 960, 1280, 1600, 1920.

The multiples of 64 are: 64, 128, 192, 256, 320, 384.... 448,512,576,640
40, 80, 120, 160, 200, 240, 280, 320, 360, 400.
No number has the multiples of 1, 2, 4, 5, 8, 10, 16, 20, 40, 80, but the number 80 (and all its multiples: 160, 240, 320, 400, ...) has them all as FACTORS.
The multiples of 64 are 64, 128, 192, 256, 320, 384, 448, and so on.
3/8 of 320 = 320*3/8 = 120
320
All multiples of 8 are also multiples of 2, but not all multiples of 2 are multiples of 8.
8 x 320 = 2560
8/320 x 100 = 2.5 Therefore, 8 is 2.5 percent of 320.
