Example Question: What is the sum of the prime factors of 7686? Example

To find the prime factors of 7686, we divide it by prime numbers starting from 2. 7686 ÷ 2 = 3843, which is not divisible by 2. Dividing by 3, we get 3843 ÷ 3 = 1281, still not divisible. Next, dividing by 5 gives 1281 ÷ 5 = 256.2, not divisible either. Continuing this process, we divide by 7, obtaining 256 ÷ 7 = 36.57. Now, dividing by 11 leads to 36 ÷ 11 = 3.2727. After dividing by 13, we have 3.2727 ÷ 13 = 0.2511. Hence, the prime factors are 2, 3, 7, 11, and 13. Finally, the sum of these factors is 2 + 3 + 7 + 11 + 13 = 36.

What is the sum of all the digits in the number 7686?

The sum of all the digits in the number 7686 is 27. To find this, we add 7 + 6 + 8 + 6 = 27.

Math Question: What is the sum of the digits in the number 7686, when each digit is cubed and then subtracted by its reciprocal?

To find the sum, start by cubing each digit and then subtracting its reciprocal: For 7: 7^3 - 1/7 = 343 - 1/7 = 343 - 1/7 For 6: 6^3 - 1/6 = 216 - 1/6 = 216 - 1/6 For 8: 8^3 - 1/8 = 512 - 1/8 = 512 - 1/8 For 6: 6^3 - 1/6 = 216 - 1/6 = 216 - 1/6 Now sum up the results: 343 - 1/7 + 216 - 1/6 + 512 - 1/8 + 216 - 1/6. Combining like terms: 343 + 216 + 512 + 216 - 1/7 - 1/6 - 1/8 - 1/6. In decimals: 343 + 216 + 512 + 216 - 0.1429 - 0.1667 - 0.125 - 0.1667. Calculating: 343 + 216 + 512 + 216 - 0.1429 - 0.1667 - 0.125 - 0.1667 = 1438.1996. Therefore, the sum of the digits in the number 7686, after cubing and subtracting by their reciprocal, is approximately 1438.1996.
