1. The problem is to find the sum of the following numbers: 6,000,000; 625,000; 100,000; 280,000; 105,000; 10,000; 160,000; 30,000; 150,000; 100,000; 130,000; 50,000; 90,000; 486,000; 240,000. 2. To find the sum, we add all the numbers together using the formula for addition: $$\text{Sum} = a_1 + a_2 + a_3 + \cdots + a_n$$ where $a_1, a_2, \ldots, a_n$ are the numbers to be added. 3. Adding the numbers step-by-step: $$6,000,000 + 625,000 = 6,625,000$$ $$6,625,000 + 100,000 = 6,725,000$$ $$6,725,000 + 280,000 = 7,005,000$$ $$7,005,000 + 105,000 = 7,110,000$$ $$7,110,000 + 10,000 = 7,120,000$$ $$7,120,000 + 160,000 = 7,280,000$$ $$7,280,000 + 30,000 = 7,310,000$$ $$7,310,000 + 150,000 = 7,460,000$$ $$7,460,000 + 100,000 = 7,560,000$$ $$7,560,000 + 130,000 = 7,690,000$$ $$7,690,000 + 50,000 = 7,740,000$$ $$7,740,000 + 90,000 = 7,830,000$$ $$7,830,000 + 486,000 = 8,316,000$$ $$8,316,000 + 240,000 = 8,556,000$$ 4. Therefore, the sum of all the numbers is: $$\boxed{8,556,000}$$
