What is the sum of the prime numbers between 1907 and 2007 inclusive?

To find the sum, we need to identify the prime numbers in the given range. Starting from 1907, we check each number until 2007. The prime numbers in this range are 1913, 1931, 1933, 1949, 1951, 1973, 1979, 1987, 1993, and 1997. The sum of these primes is 19526.

Math question: What is the sum of the digits of the number 1907?

To find the sum of the digits in 1907, we add 1 + 9 + 0 + 7 = 17.

Math question: What is the sum of the prime factors of the number 1907?

To find the prime factors, we start by checking for divisors up to the square root of 1907, which is approximately 43. Starting with the smallest prime, 2, this does not divide evenly into 1907. Moving to the next prime, 3, we find that it does not divide either. Continuing this process, we find that 5, 7, 11, 13, 17, 19, and 23 are also not divisors of 1907. However, when we reach 29, we find that it does divide evenly into 1907 (as 29 x 67 = 1907). Therefore, the prime factors of 1907 are {29, 67}. The sum of these prime factors is 29 + 67 = 96. Thus, the sum of the prime factors of 1907 is 96.
