1 x 18, 2 x 9, 3 x 6, 6 x 3, 9 x 2, 18 x 1
The factors of 18 are 1, 2, 3 , 6, 9 & 18 because: 1 x 18 = 18 2 x 9 = 18 3 x 6 = 18
1, 2, 3, 6, 9, 18: (1 x 18, 2 x 9, 3 x 6, 6 x 3, 9 x 2, 18 x 1)
18 = 1 x 18, 2 x 9, 3 x 6, 6 x 3, 9 x 2, 18 x 1.
18 = 9 x 2, so LCM of 18 & 9 is 18. 8 = 2 x 2 x 2; so 18 & 8 share a common factor of 2, so the LCM = 18 x 2 x 2 = 72.
18 = 1 x 18, 2 x 9, 3 x 6, 6 x 3, 9 x 2, 18 x 1.
1 x 18, 2 x 9, 3 x 6, 6 x 3, 9 x 2, 18 x 1

1 x 18 2 x 9 3 x 6 2 x 3 x 3
1, 2, 3, 6, 9, 18: 1 x 18, 2 x 9, 3 x 6
If you want to stick to integers: 1 x 18 = 18 2 x 9 = 18 3 x 6 = 18 -1 x -18 = 18 -2 x -9 = 18 -3 x -6 = 18
No, 18 is a multiple of 9. (18 = 2 x 9, so 2 and 9 are factors of 18).
3x = 2 x 9 2 x 9 = 18 3x = 18 18/x = 6 Therefore, x = 6
9 x 2 = 18
