Question: What is the largest prime factor of the number 1999?

To find the largest prime factor of 1999, we need to factorize the number. First, we check if 2 is a factor, but 1999 is an odd number, so it is not divisible by 2. Next, we check divisibility by prime numbers up to the square root of 1999, which is approximately 44.72. We start with 3, and find that 1999 ÷ 3 = 666.33, which is not an integer. Then we move to the next prime number, 5, but 1999 ÷ 5 = 399.8, again not an integer. Following this process, we eventually find that 1999 is indivisible by all prime numbers up to its square root. Therefore, it must be a prime number itself. Hence, the answer is that 1999 is actually a prime number, with no factors other than itself and 1.

Math question: What is the product of the prime factors of the number obtained by adding 1999 to its reverse?

To find the number obtained by adding 1999 to its reverse, we reverse 1999 and add it to the original number: 1999 + 9991 = 11990. Next, let's factorize 11990 into its prime factors: 2 × 5 × 7 × 7 × 17. The product of these prime factors is calculated by multiplying them together: 2 × 5 × 7 × 7 × 17 = 119,770. Therefore, the product of the prime factors of the number obtained by adding 1999 to its reverse (11990) is 119,770.

Math Question: What is the sum of all the prime numbers from 1 to 1999?

To find the sum of prime numbers from 1 to 1999: 1. Start by listing all the prime numbers within this range: 2, 3, 5, 7, 11, 13, 17, 19, 23, 29, ... (and so on). 2. To determine if a number is prime, check divisibility by prime numbers less than its square root. 3. Sum up all the prime numbers within this range. 4. The sum of the prime numbers from 1 to 1999 is: 84,502.
