Because 6 and 8 both go into 24.
7 and 8 both go into 56
all you have to do is find a number (not one) that will go into 6 and 8. 2 goes into both of them, so it would be 3:4.
1 and 2 can go into both without a remainder.
24, 48, 72, 96, 120, 144 +24 . . .
They both go into 1440, for example.
Both 8 and 6 are multiples of 2.
(z - 8) / 6 = -4 Multiply both sides by 6: (z - 8) = -24 Add 8 to both sides: z = -16
what can 8, 6 and to all go into
7 is co-prime to both 6 and 8.
LCM(6, 8) = 24
-x/6 - 8 = 0 Add 8 to both sides: -x/6 = 8 Multiply both sides by 6: -x = 48 Change the sign on both sides x = -48
