Math Question: What is the largest prime factor of the number obtained by reversing the digits of 1611?

To find the largest prime factor of 1161, we need to reverse the digits, resulting in the number 1161. Factors of 1161 include 1, 3, 387, and 1161 itself. The largest prime factor would be 387 since it cannot be broken down into smaller prime factors. Therefore, the largest prime factor of the reversed number 1611 is 387.

Question: What is the sum of the first 1611 positive even integers?

To find the sum of the first 1611 positive even integers, we use the formula for the sum of an arithmetic series: S = (n/2)(first term + last term), where S is the sum, n is the number of terms, and the first and last terms are given by 2 and (2n), respectively. In this case, we have n = 1611, so the first term is 2 and the last term is 2(1611) = 3222. Plugging these values into the formula, we get: S = (1611/2)(2 + 3222) = (1611/2)(3224) = 2598642. Therefore, the sum of the first 1611 positive even integers is 2,598,642.

What is the sum of the digits of the number 1611?

To find the sum of the digits, add the individual digits together. In this case, 1 + 6 + 1 + 1 equals 9.
