8
For the values 12, 8 the LCM is: 24The LCM of 8 and 12 is 24, which is the multiple of the highest power of prime factors from both numbers (23 x 3 = 2 x 2 x 2 x 3 = 12). (Prime factors: 8 = 23; 12 = 22 x 3)
(24/8) x 22 = 3 x 4 = 12
x - 8 = 12 x - 8 + 8 = 12 + 8 x = 20
1 x 22 = 22 2 x 22 = 44 3 x 22 = 66 4 x 22 = 88 5 x 22 = 110 6 x 22 = 132 7 x 22 = 154 8 x 22 = 176 9 x 22 = 198 10 x 22 = 220 11 x 22 = 242 12 x 22 = 264
Floor area = ceiling area = 11 x 8 = 88 sq feet Wall area = 2 x 11 x 12 + 2 x 8 x 12 = (22 + 16) x 12 = 38 x 12 = 456 sq feet
-8 x -11 + (-22) = 88 - 22 = 66
22 x 8 = (20 x 8) + (2 x 8) = 160 + 16 = 176
12 x 22 = 264
12 x 22 = 264
