Math question: What is the sum of the prime factors of the number 1271?

To find the prime factors of 1271, we can factorize it by dividing it successively by prime numbers. By doing so, we find that 1271 = 7 * 13 * 13. Therefore, the prime factors of 1271 are 7 and 13. The sum of these prime factors is 7 + 13 = 20. Additionally, we notice that 1271 is also a prime number itself, satisfying the conditions of a prime factor. So, the sum of all prime factors, including the number itself, is 7 + 13 + 1271. Evaluating this gives us a sum of 1291. Hence, the sum of the prime factors of 1271 is 20, while the sum of all the prime factors, including the number itself, is 1291.

Math question: What is the sum of the digits of the number 1271?

To find the sum of the digits in 1271, we add each individual digit: 1 + 2 + 7 + 1 = 11. Therefore, the sum of the digits in the number 1271 is 11. The sum of the digits can provide valuable insights into the divisibility and properties of numbers.

Math question: If 1271 is divided by 7, and then multiplied by 3, what is the result?

To find the result, we divide 1271 by 7, which gives us 181.57 (rounded to two decimal places). Multiplying this result by 3, we get 544.71 (rounded to two decimal places). Therefore, the result of dividing 1271 by 7 then multiplying by 3 is approximately 544.71.
