What is the sum of the digits in the number 3129 after squaring it and dividing the result by the product of the digits?

To solve this problem, we start by squaring the number 3129, which gives us 9768241. The next step is to find the product of the digits in 3129, which is 3 * 1 * 2 * 9 = 54. We then divide the squared number by the product: 9768241 / 54 = 181127. Then, we sum up the digits in 181127, which is 1 + 8 + 1 + 1 + 2 + 7 = 20. Therefore, the final answer is 20.

Math Question: What is the sum of the digits in the number 3129?

To find the sum of the digits in 3129, we can add the digits individually. The digit 3 + 1 + 2 + 9 equals 15. Therefore, the sum of the digits in 3129 is 15. This means that if we add 3 + 1 + 2 + 9 together, the result will be 15.

Math question: What is the largest prime factor of 3129?

To find the largest prime factor of 3129, we can start by dividing it by 2 which gives us 1564.5. Since 1564.5 is not an integer, we continue to divide by the next prime, which is 3. Dividing 3129 by 3 gives us 1043. 1043 is still not divisible by 3, so we move on to the next prime, which is 5. Dividing 1043 by 5 gives us 208.6. Again, this is not an integer, so we proceed with dividing by the next prime, which is 7. Dividing 208 by 7 gives us 29.7143, which is not an integer either. Finally, we try dividing by 11, the next prime number. Dividing 29 by 11 gives us 2.6363... Since 2 is a prime number, we have found the largest prime factor of 3129 to be 2. Thus, the largest prime factor of 3129 is 2.
