Question: The number 1897 is a prime number. What is the nearest number, greater than 1897, that is also a prime number?

To find the nearest prime number greater than 1897, we start checking numbers sequentially. Starting from 1898, we divide each number by all positive integers less than itself, up to the square root of the number. After checking several numbers, we find that 1901 is the nearest prime number greater than 1897. It is confirmed by dividing 1901 by all positive integers less than its square root. Therefore, 1901 is the answer.

Math question: What is the sum of all the positive factors of 1897?

To find the sum of factors, we need to prime factorize the number. Since 1897 is a prime number, its only factors are 1 and 1897 itself. Thus, the sum of factors of 1897 is 1 + 1897 = 1898. The prime factorization of 1897 is 1897 = 1 × 1897. Therefore, it has only two distinct factors, making the sum quite simple.

Math question: What is the remainder when 1897 is divided by 13?

The number 1897 can be divided by 13 to give a quotient of 145 and a remainder of 2. Thus, the remainder when 1897 is divided by 13 is 2.
