To divide 15 and 8 by 2, we simply divide their respective values by 2, as follows:

15 ÷ 2 = 7.5
8 ÷ 2 = 4


To find the square of 15 and 8, we simply multiply each value by itself, as follows:

15² = 225
8² = 64


The LCM (Least Common Multiple) is the smallest number that is a multiple of both 15 and 8. To find the LCM, we can use the following steps:

1. List the multiples of the larger number (15) until you find a multiple of the smaller number (8):
15, 30, 45, 60, 75, 90, 105, 120, 135, 150, 165, 180, 195, 210, 225, 240, 255, 270, 285, 300...

2. Find the multiple of the larger number that is also a multiple of the smaller number (8):
8 × 30 = 240

3. Therefore, the LCM of 15 and 8 is 240.


After dividing 15 and 8 by 2, we find that their values are 7.5 and 4, respectively. Then, we find the square of each value, which is 225 and 64. Finally, we calculate the LCM of 15 and 8, which is 240. Therefore, the final answer is:

7.5, 4, 225, 64, 240
